Question

The refractive index of Glass with respect to air is 1.5 and refractive index of water is 1.3, state giving reason that total internal reflection of ray of light entering from glass into water possible or not?​

Answer 1

Answer:

It is possible

Explanation:

Two very important conditions for total internal refraction are:

1) Ray must be traveling from denser to rarer medium (since glass is denser (n=1.5) than water (n=1.3) therefore it is possible.

2) angle of incidence must be greater than critical angle.
