Question

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

• A. v(A) > v(B) and n(A) > n(B)
• B. v(A) > v(B) and n(A) < n(B)
• C. v(A) < v(B) and n(A) > n(B)
• D. v(A) < v(B) and n(A) < n(B)

Answer 1

The correct option is B

v(A) > v(B) and n(A) < n(B)
