Physics Laboratory Equipment : A complete list of important equipment and their uses

In most Physics labs, you'll encounter some basic common apparatus. In this blog, you will find a picture and an explanation for how to use each of these equipment. Physics is the natural science that studies matter , its motion and behavior through space and time and that studies the related entities of energy and force. Physics is one of the most fundamental scientific disciplines, and its main goal is to understand how the universe behaves. Its scope further trickles down to not only the behavior of objects under the action of given forces but also the nature and origin of gravitational, electromagnetic, and nuclear force fields.

Theory and experiment go hand in hand. An experiment that results in measurement of a phenomena can predict or confirm a theory. While a theory that predicts the outcome of an experiment is considered valid.

And these list of equipment do just that by providing the measurement of phenomena in a controlled environment. A resistor is an electrical component that provides electrical resistance in a circuit. It is used to reduce current flow, adjust signal levels, to divide voltages, bias active elements etc.

A rheostat is a variable resistor which is used to control current. It can vary the resistance in a circuit by wiper sliding contact mechanism. You can read more about it here. A multimeter is an electronic measuring instrument that combines several measurement functions in one unit. It can measure voltage, current, and resistance. Analog multimeter uses moving pointer to display readings while digital version displays it on a screen.

A voltmeter is an instrument used for measuring electrical potential difference between two points in an electric circuit. Analog voltmeters move a pointer across a scale in proportion to the voltage of the circuit while digital voltmeters give a numerical display of voltage by use of an analog to digital converter.

An ammeter is an instrument used to measure the current, either direct or alternating electric current, in a circuit. Electric currents are measured in amperes A , hence the name. Analog ammeters move a pointer across a scale in proportion to the current of the circuit while digital ammeters give a numerical display of current by use of an analog to digital converter.

The galvanometer is the device used for detecting the presence of small current and voltage or for measuring their magnitude. The galvanometer is mainly used in the bridges and potentiometer where they indicate the null deflection or zero current.

It works as an actuator, by producing a rotary deflection of a "pointer" , in response to electric current flowing through a coil in a constant magnetic field. A potentiometer is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider.

If only two terminals are used, one end and the wiper, it acts as a variable resistor or rheostat. A battery eliminator is a device powered by an electrical source other than a battery, which then converts the source to a suitable DC voltage that may be used by a second device designed to be powered by batteries. The Daniel cell is a type of electrochemical cell. It consists of a copper pot filled with cuprous sulfate solution, in which was immersed an unglazed earthenware container filled with sulfuric acid and a zinc electrode.

Zinc sulfate may be substituted for the sulfuric acid. The chemistry of this cell was later successfully adapted to manufacture a dry cell. Meter Bridge is an instrument that is used to find the unknown resistance of a coil or any other material.

This bridge works under the principle of Wheatstone bridge. We know that the Wheatstone Bridge is used to measure the unknown resistance connected in a circuit. It consists of four resistors of which two resistors are known Resistors, one variable resistor and one unknown resistor along with a galvanometer.

Meter bridge acts as the variable resistance. It consists of a wire whose length is one meter and has uniform cross sectional area, stretched along a meter scale.

The bridge has two metallic strips which is in reverted L shape on either side of the wire. These metallic strips act as holders for the wire. The wire is being clamped to the strips. These two metallic strips are made up of metals like copper. The bridge consists of another metallic strip which is placed between those two strips with a gap between them.

So totally there are five leads on the bridge which are then connected to one known resistor, one unknown resistor and one galvanometer and thus forming Wheatstone bridge. The constant of proportionality is called the "resistance", R.

The apparatus consists of one wire wound rheostat, one moving coil voltmeter and one moving coil ammeter, mounted on a bakelite plate in a wooden case. With four terminals, two for battery connection and two for resistance coil.

A compass is an instrument that shows directions. It has a needle, called a compass rose, which points in North-South direction. The "N" mark on the rose points northward. Compasses often display markings for angles in degrees in addition to the rose. A magnet is a material or object that produces a magnetic field that exerts a force, called magnetic force, which pulls on other ferromagnetic materials, such as iron, and attracts or repels other magnets.

It has two poles called North and South pole. A prism is a transparent optical element with flat, polished surfaces that refract light. At least two of the flat surfaces must have an angle between them. The traditional geometrical shape is that of a triangular prism with a triangular base and rectangular sides.

Prisms can be made from any material that is transparent to the wavelengths for which they are designed. Typical materials include glass, plastic, and fluorite. It can be used to split light into its constituent spectral colours the colours of the rainbow where each colour has different wavelengths.

A lens is an optical device that focuses or disperses a light beam by means of refraction. A lens can focus light to form an image, unlike a prism, which refracts light without focusing. Lenses are made from materials such as glass or plastic, and are ground and polished or moulded to a desired shape.

Lenses are classified by the curvature of the two optical surfaces. A lens is biconvex or double convex, or just convex if both surfaces are convex. A lens with two concave surfaces is biconcave or just concave. If one of the surfaces is flat, the lens is plano-convex or plano-concave depending on the curvature of the other surface.

A lens with one convex and one concave side is convex-concave or meniscus. It is this type of lens that is most commonly used in corrective lenses. A mirror is an object that reflects light in such a way that, for incident light in some range of wavelengths, the reflected light preserves many or most of the detailed physical characteristics of the original light, called specular reflection. The most familiar type of mirror is the plane mirror, which has a flat surface.

Curved mirrors like concave or convex mirrors are used to produce magnified or diminished images or focus light.

The optical bench is a long steel pipe with a linear scale applied to it. It consists of holders for light sources, lenses and screens are placed on the apparatus so that image formation can be observed. An object is put on one side and corresponding image distance can be measured. A pendulum is a weight suspended from a pivot so that it can swing freely.

When a pendulum is displaced sideways from its resting, equilibrium position, it is subject to a restoring force due to gravity that will accelerate it back toward the equilibrium position.

When released, the restoring force acting on the pendulum's mass causes it to oscillate about the equilibrium position, swinging back and forth. Parallelogram apparatus is used in measuring forces acting on a single point. It consists of a black board of around xmm with 2 aluminium pulleys clamped at the top.

A spool of thread passes through these pulleys. Three hangers are connected to the spool and carry different slotted weights.

A tuning fork is a two-pronged fork with the prongs tines formed from a U-shaped bar of elastic metal. On striking these tines against a surface, it resonates at a specific constant pitch.

The pitch that a particular tuning fork generates depends on the length and mass of the two prongs.

The back and forth vibration of the tines produce disturbances of surrounding air molecules. As a tine stretches outward from its usual position, it compresses surrounding air molecules into a small region of space; this creates a high pressure region next to the tine.

As the tine then moves inward from its usual position, air surrounding the tine expands; this produces a low pressure region next to the tine. The high pressure regions are known as compressions and the low pressure regions are known as rarefactions. As the tines continue to vibrate, an alternating pattern of high and low pressure regions are created. These regions are transported through the surrounding air, carrying the sound signal from one location to another.

Electrical input is made via two 4mm sockets and the mechanical output is provided by a shaft terminating in a pair of clamping nuts. Wave Motion Apparatus is used fordemonstrating longitudinal and transverse motion. It consists of a number of eccentric discs supporting a series of metal rods on revolving the handle, transverse waves are obtained.

Longitudinal waves are obtained with bent rods running in metal guide on metal base. A resonance apparatus is used in locating resonance positions in air columns. These resonance positions help in calculating the speed of sound using the water level and the frequency of the tuning fork used.

A Sonometer is a device for measuring the relationship between the frequency of the sound produced by a plucked string and the tension, length and mass per unit length of the string.

Godfrey Tanya Course Expectations.

Я был ослеплен своими амбициями. Ее тревога не была напрасной. Дэвид в опасности… или того хуже. Быть может, уже поздно.

Несмотря на сомнения относительно быстродействия машины, в одном инженеры проявили единодушие: если все процессоры станут действовать параллельно, ТРАНСТЕКСТ будет очень мощным. Вопрос был лишь в том, насколько мощным. Ответ получили через двенадцать минут. Все десять присутствовавших при этом человек в напряженном ожидании молчали, когда вдруг заработавший принтер выдал им открытый текст: шифр был взломан. ТРАНСТЕКСТ вскрыл ключ, состоявший из шестидесяти четырех знаков, за десять с небольшим минут, в два миллиона раз быстрее, чем если бы для этого использовался второй по мощности компьютер АНБ.
