Figure shows a ray of light AO incident on a rectangular glass block PQRS, which is silvered at the surface RS. The ray is partily reflected and partly refracted.
(a) Draw the path of the reflected and refracted rays.
(b) Show at least two rays emerging from the surface PQ after reflection from the surface RS.
(c) How many images are formed in the above case ? Which image is the brightest ?

Text Solution

Verified by Experts

(a) The completed diagram is as drawn here. OB is the reflected ray and OC is the refracted ray for the incident ray AO.

(b) Rays 1 and 2 are the two rays emerging from the surface PQ after reflections from the surfaces RS.
(c) Multiple (or infinite) images are formed at C at the silvered surface RS is the brightest. it is seen in the direction of ray 1.
