The law of reflection states that if the angle of incidence is 40 degrees, the angle of reflection is degrees.

Answer

40 degrees

Explanation

When waves hit a surface they get reflected. The law of reflection states that the angle of incidence is equal to the angle of reflection. In this case, the law of reflection tells us that if the angle of incidence is 40 degrees, the angle of reflection is 40 degrees.
