Question

Using Huygen's principle when an oblique wavefront is incident on the reflecting surface making an angle
of incidence i with the surface, show that it gets reflected making the same angle​

Answer 1

Answer:

That is, incident wavefront AB and reflected wavefront A'B' make equal angles with the reflecting surface XY. As the rays are always normal to the wavefront, therefore the incident and the reflected rays make equal angles with the normal drawn on the surface XY. This is the second law of reflection.
