Show that for a given incident ray, if the mirror is rotated by an `angle theta`, the reflected ray rotates by `2theta`.

What is incident ray and reflected ray?

When a light ray in air is incident on glass at 57^(@) , the reflected ray is completely polarised. If the same ray is incident on water at an angle theta , also the reflected ray is completely polarised. Then

In the adjacent figure PQ and RS are two mirrors placed parallel to each other. An incident ray AB strikes the mirror PQ at B, the reflected ray moves along the path BC and strikes the mirror RS at C and again reflected back along CD . Prove that AB || CD.

A mjrror is turned through 15^@ . By what angle will the reflected ray turn?

If a light ray is incident on a horizontal plane mirror making an angle 30^(@) with the mirror, what angle will the reflected ray make with the mirror ?

A ray of light travelling through a denser medium is incident at an angle I in a rarer medium. If the angle between the reflected ray and refracted ray is 90^(@) , show that the critical angle of the two media, theta_(c) = sin^(-1) (tan i)

If ray of light falls on a mirror at 30^@ angle the reflected angle becomes_______

Two plane mirrors are inclined to each other at an angle theta .A ray of light is reflected first at one mirror and then at the other . The total deviation of the ray is

If a ray of light is incident on a reflecting medium at the polarising angle, prove that the reflected and the refracted rays are at 90^(@) to each other.
