Question

A rauy of light is incident on a flat reflecting surface and makes an angle of 38∘ with the surface. What is the angle of reflection for the reflected ray? (Round off answer to the nearest degree and write degrees for units in your answer.)

Answer 1

The angle of reflection for a light ray incident at a 38° angle with a flat reflecting surface, according to the Law of Reflection, is 52°.

Step-by-step explanation:

The angle of reflection for a ray of light that is incident on a flat reflecting surface is determined by the Law of Reflection. According to this law, the angle of reflection is equal to the angle of incidence. Since the light is incident at a 38° angle to the surface, the angle of incidence, which is measured relative to the perpendicular to the surface, is 52° (since 90° - 38° = 52°). Hence, the angle of reflection, also measured from the normal, will be 52° as well. When you round this to the nearest degree, it remains 52°.
