Optics Question 713

Question: A beam of light propagating in medium A with index of refraction n passes across an interface into medium B with index of refraction n. The angle of incidence is greater than the angle of refraction; v and v denotes the speed of light in A and B. Then which of the following is true

Options:

A) v > v and n > n

B) v > v and n < n

C) v < v and n > n

D) v < v and n < n

Show Answer

Answer:

Correct Answer: B

Solution:

Q Ð i > Ð r, it means light ray is going from rarer medium to denser medium. So $ v(A)>v(B) $ and $ n(A)<n(B) $
