great ans
can u tell me about the examples
hydrogen and helium is an example
diamond and moissanite are also a pair of nice examples
The answer is (b) will be smaller than the angle of refraction.
because the light ray is travelling from a medium of higher refractive index(glass) to a medium of lower refractive index (air), it shall bend away from the normal and hence the angle of refraction will be greater than the angle of incidence.
