A
B
C
D
None of these
Text Solution
Verified by ExpertsThe correct answer is:
A
When a ray of light passes from a denser medium to a rarer medium, then it bends away from the normal at the interface of the two media.
The angle of incidence is measured with respect to the normal at the refractive boundary. It is given by
where, C is critical angle, 
is the refractive index of rarer medium and 
of the denser medium.
Given,
