A light ray passing from air into water at an angle of 30º from the normal in air would
A
make an angle greater than 30\(^0\) in water surface
B
be completely absorbed by the water surface
C
be completely reflected by the water surface
D
make an angle less than 30\(^0\) from the normal in water
Verified Correct Answer: D.
Physical Principles & Numerical Solution
Observations show that when the light travels from a medium A(air) to a more dense medium B(water), the refracted ray bends towards the normal and the angle of refraction (r) is, therefore, less than the angle of incidence. vice versa.
