A light ray hits a hard, opaque object. The angle at which the light ray bounces off the object depends on

The law of reflection says the angle of reflection equals the angle of incidence, measured from the normal to the surface. So the direction the ray bounces off depends on the angle at which it hits the surface. Surface smoothness affects whether the reflection is regular or scattered, but not this basic angle rule.
