(a) Define refraction and state at least three examples of refraction. (b) Describe dispersion of white light into its constituent colours.

State the laws of refraction of light. State at least three examples of refraction of light.

The refractive index of the material of a prism is 1.5 and its refracting angle is 6º. Find the deviation produced by the prism for a small angle of incidence.

The refractive index of the material of a prism is 1.5 and its refracting angle is 6º. Find the deviation produced by the prism for a small angle of incidence.

A convex lens is dipped in a liquid whose refractive index is equal to the refractive of the lens. Then its focal length will

How is a wavefront defined? Using Huygen's construction , draw a figure showing the propagation of a plane wave refracting at a plane surface separating two media. Hence verify Snell's law of refraction.

The index of refraction can be defined as the velocity of light In a vacuum divided by the velocity In the medium (N=C/S) If this is the case, another valid expression for Snell's law Is
