Answer 1

Reflection: The process of sending back the light rays which fall on polished surface is called reflection of light.
Laws of reflection:
(i) The angle of reflection is always equal to the angle of incidence.
(ii) The incident rays, reflected rays and the normal, all lie in the same plane.

An ideal mirror:

The angle between incident ray and reflected ray is $90^{o}$ . Find the angle of reflection.

If $x = 3 7^{o}$ , Find $L i, L r$ & $L x$

State whether true or false:
If the light from a flashlight hits a mirror at a $6 0^{o}$ angle, the angle of the reflected beam will be $12 0^{o}$ .
