Define refraction of light and explain the relation between refractive index of material and velocity of light.

Refractive index depends on the velocity of light.

What is refraction of light? How is refractive index of material related to velocity of light?

The relation between refractive index of the medium and angle of polarisation is called

A ray of light is incident on a glass slab making an angle of 25^@ with the surface. Calculate the angle of refraction in glass and velocity of light in glass, if the, refractive index of glass and velocity of light are 1.5 and 3 xx 10^8 m/s respectively.

The ratio of the refractive index of red light to blue light in air is

Explain refractive index using water.

Explain Refraction of Light at a plane boundary between two media.

Distinguish between Reflection of light and refraction of light :

A ray of light is incident normally on one face of a prism of refracting angle A. After travelling through prism, the ray emerges from the second refracting surface making an angle of deviation of delta . The refractive index of the material of prism is

Answer the following questions Obtain the relation between the refractive index of the second medium with respect to the first medium and the refractive index of the first medium with respect to the second medium.
