Optics Question 827
Question: A equilateral prism is made of a transparent material of refractive index $ \sqrt{2} $ . A ray of light AB is incident at $ 45{}^\circ $ as shown. The net deviation in the path of ray when it comes out of prism is
Options:
A) $ 135{}^\circ $
B) $ 120{}^\circ $
C) $ 30{}^\circ $
D) $ 150{}^\circ $
Show Answer
Answer:
Correct Answer: D
Solution:
[d] $ \delta =( 45{}^\circ -30{}^\circ )+( 180{}^\circ -60{}^\circ )+( 45{}^\circ -30{}^\circ ) $
$ =150^\circ $ Clockwise.
