Question

If a light wave is reflected with a 27° angle of reflection, what was the angle of incidence of which it was transmitted?

a.117°
b.153°
c.27°
d.63°

Answer 1

c.27°

Step-by-step explanation:

The law of reflection states that the angle of reflection will be equal to the angle of incidence. That means if the lightwave reflected as 27°, then the angle of incidence will be 27° too.

But most things have an irregular surface on a microscopic level so some of the light will be scattered diffusely.
