The refractive indices of glass and water w.r.t. air are 3/2 and 4/3 respectively. Determine the refractive index of glass w.r.t. water.
The refractive indices of water for red and violet colours are 1.325 and 1.334 respectively.
Find the difference between the velocities of rays for these two colours in water. (c = 3 × 108 m/s)
A ray of light passes from a vacuum to a medium of refractive index (μ). The angle of
incidence is found to be twice the angle of refraction. The angle of incidence is _______.
C) `2 cos^(-1) (mu/2)`
D) `2 sin^(-1) (mu/2)`
The glass plate of refractive index 1.732 is to be used as a polarizer, its polarising angle is _______.
