Angle of incidence is equal to angle of reflection

Angle of incidence is equal to the angle of reflection.

State Huygens' principle and use it to describe the process of reflection of a parallel beam of light incident on a plane mirror obliquely with the help of a labelled diagram.Prove that the angle of incidence is equal to the angle of reflection.

How is a wavefront defined? Using Huygens' prniciple draw a figure showing the propagation of a plane wave reflecting at the interface of the two media. Show that the angle of incidence is equal to the angle of reflection.

When a ray of light passes through a parallel slab of transport medium, then show that angle of incidence is equal to angle of emergence.

A ray of light passes through an equilateral glass prism,such that angle of incidence is equal to the angle of emergence.If the angle of emergence is 3//4 times the angle of prism,calculate the refractive index of the glass prism.

A ray of light passes through an equilateral glass prism, such that angle of incidence is equal to the angle of emergence. If the angle of emergence is 3//4 times angle of prism, calculate the refractive index of the glass prism.

A ray of light falls on a mirror normally.What are the values of the angle of incidence and the angle of refelection?
