When a light ray strikes a smooth, flat surface, what is the relationship between the angle of incidence and the angle of reflection?
They are equal.
The angle of incidence is twice that of the angle of reflection.
The angle of reflection is twice that of the angle of incidence.
They combine to add up to 180o.
