Light travels in two media A and B with speeds 
respectively. Then the critical angle between them is:
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
: Here, 
Light travels slower in denser medium. Hence medium A is a denser medium and medium B is a rarer medium, Here, light travels from medium A to medium B. Let C be the critical angle between them.
Refractive index of medium B w.r.t. to medium A is
or
