Properties of images formed by a plane mirrors: i The image formed by a plane mirror is virtual and erect. Properties of the image formed by a convex mirror: i This image is always virtual and erect. Laws of refraction of light: The refraction of light obeys the following two laws: First law: The incident ray, the refracted ray and normal to the surface of separation at the point of incidence, all lie in the same plane. Second law: The ratio of the sine of the angle of incidence and the sine of the angle of refraction is constant for a given pair of media.

These multiple choice type questions are perfect to revise all the fundamental concepts occurring in the chapter and prepare the objective type questions for CBSE Class 10 Science Exam An object is placed 20 cm in front of a plane mirror. The mirror is moved 2 cm towards the object. The distance between the positions of the original and final images seen in the mirror is:. A ray of light that strikes a plane mirror PQ at an angle of incidence of 30 o , is reflected from the plane mirror and then strikes a second plane mirror QR placed at right angles to the first mirror.
