Question

a wave is incident on the surface of a mirror at an angle of 30 degree with the normal. At what angle will the outgoing wave reflect ?

Answer 1

Answer: The angle of reflection is 30°

Step-by-step explanation:

The law of reflection implies that an angle of reflection is the same as an angle of incidence.

Angles of reflection and inci9are both measured from a straight line perpendicular to the mirror called normal at the point of intersection.

For a plain mirror, these angles are equal.

Therefore the angle of reflection is 30°.

Answer 2

The angle will reflect will be equal to the angle of incidence. Which means that it will be reflected at an angle 30 degrees from the normal angle.

Hope this helps!!
