The speed of light in media M 1 and M 2 are 
and 
respectively. A ray of light enters from medium M 1 to M 2 at an incidence angle i. If the ray suffers total internal reflection, the value of i is
A
Equal to 
B
Equal to or less than 
C
Equal to or greater than 
D
Less than 
Text Solution
Verified by ExpertsThe correct answer is:
C
Given, 
Refractive index for medium M 1 is
Refractive index for medium M 2 is
If i is the angle of incidence and C is the critical angle then for total intenal reflection
But
