Define Law of refraction

State the Laws of Refraction.

State and explain laws of refraction of light.

Explain Refraction of light on the basis of Wave Theory. Hence prove the Laws of Refraction.

Derive the laws of refraction of light using Huygen's principle.

If hat(i) denotes a unit vector along incident light ray, hat( r) a unit vector along refracted ray into a medium of refractive index mu and hat(n) unit vector normal to boundary of medium directed towards incident medium, then law of refraction is

Define absolute refractive index and relative refractive index. Explain in brief with an illustration for each.

A ray of light is incident on the surface of a glass plate of index of refraction 1.55 at the polarizing angle. Calculate the angle of refraction.

What are laws of reflection and refraction ?

Answer the following questions Define absolute refractive index.

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