What is critical angle?

A ray of light is refracted from medium 1 to medium 2. Show that the ratio of the sine of the angle of incidence and the sine of the angle of refraction is equal to the ratio of velocity of light in medium 1 and that in medium 2.

Statement I : Relative refractive index of a medium can be less than unity. Statement II : The angle of incidence is equal to the angle of refraction.

Critical angle depends on

A ray of light passes through an equilateral prism in such a way that the angle of incidence becomes equal to the angle of emergence and each of these angles are (3)/(4) th of the angle of deviation. Determine the angle of deviation.

A light ray travels from vacuum into a medium of refractive index mu . If angle of incidence is twice the angle of refraction then calculate the angle of incidence.

The refractive index of a medium with respect to air is sqrt2 . If the angle of incidence of a ray of light in air is 45^@ determine the angle of deviation for that ray in case of refraction.
