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) $
