The observer at O views two closely spaced spots on a vertical wall through an angled glass slab as shown in figure. As seen by observer, the spots appear

A

shifted upward, such that distance between them remains same

B

shifted downward, such that distance between them remains same

C

spaced farther apart

D

spaced closer together

Text Solution

Verified by Experts

The correct Answer is:
a.
Emergent ray e will be parallel to incident ray i. So both dots will appear to be shifted upward by same distance. Hence, distance between them remains same.
