A beam of light propagating in medium A ...

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

u(A) `gt)` u (B) and n(A) `gt` n(B)

B

v(A) `gt` v(B) and n(A) `lt` n(B)

C

v(A) `lt` v(B) and n(A) `gt` n(B)

D

v(A) `gt` v(B) and n(A) `lt` n(B)

Text Solution

Verified by Experts

The correct Answer is:
B
`n(A) lt n(B) rArr u (A) gt v (B)`
Since, `anglei gt angler `, light going from rarer to denser medium.
