Physics Lesson 4,Light Energy Q30 What is a plane mirror ? List its uses.

Ans- A plane mirror is a mirror with a flat (planar) reflective surface. If a thin plane sheet of glass is silvered on one side then covered with a coat of some opaque substance, the other side of glass plate behaves as a reflecting surface. Uses of Plane Mirror : 1. They are used as looking glass. 2. They are used in solar cookers. 3. They are also used in constructing periscope which is used in submarines. 4. They are also used to make kaleidoscope, a toy which produces beautiful patterns. 5. Microscopes have plane mirrors to reflect light on the slides to be viewed. 7. It can be used as a simple rear view mirror by the drivers of vehicles to see objects at his back 8. It is used by an optician while testing the eye sight to double the length of his small testing room. Q31. Explain reflection of light from a plane mirror. Ans. When the light rays which gets stroked on the flat mirror and gets reflected back. According to laws of reflection, the angle of reflection is equal to the angle of incidence. The image is obtained behind the plane which is present in the mirror. This process of obtaining a mirror image which virtual and erect is known as a reflection on a plane mirror. If A ray of light is originated from a point P and strike the plane mirror at Q such that linePQ makes an angle of 90° with the mirror hen this ray of light will be returned back by the plane mirror along same path in the direction QP. But if a ray of light strikes a plane mirror at n angle of incidence less than 90° then it is reflected as per laws of reflection.
