Using Huygens principle, show that the angle of incidence is equal to angle of reflection during a plane wave front reflected by a plane surface.

Text Solution

Verified by Experts

Using Huygen.s wave theory of light, show that the angle of incidence is equal to angle of reflection in case of reflection of a plane wavefront by a plane surface.

`AE=BC=vt`
The triangles EAC and BAC are congruent and therefore, the angles i and r (as show in Fig. ) would be equal. This is the law of reflection.
