1) Describe how the pin method is used to determine the image of an objects in the mirror. 2) For any plane mirror, how far behind the mirror is the image of an object which is located in front of the mirror? 3) A ray of light is incident upon a mirror at an angle of incidence of 30 degrees. What is the angle between the incident ray and the reflected ray?

1. what is the pin method? 2. the distances are the same for a plane mirror. 3. angle of incidence = the angle of relfection

the pin method is used to mark the points. u know like when u have to reflect points across a mirror on a piece of paper.

The pin method is used to prove the law of reflection in optics. The angle of incidence is equal to the angle of reflection. So here the angle of incidence is 30degree. Hence the angle of reflection is also 30 degree. But the angle between the incident ray and the reflected ray is 2*30=60 degrees. because|dw:1336132096754:dw|
The images in the mirror are at the same distances as we see in the real object space
