Question

If a wave hits a smooth surface at an angle of incidence of 40 degrees, the angle of reflection is

Answer 1

Answer:

Angle of reflection will be $40^{\circ}$

Explanation:

We have given angle of incidence from the smooth surface is $40^{\circ}$

So angle of incidence = $40^{\circ}$

We have to find the angle of reflection

From l;aw of reflection we know that angle of reflection is equal to the angle of incidence

So angle of reflection will be equal to $40^{\circ}$
