Question

The law of reflection states that
light travels in a straight line
light must be reflected into our eyes to be seen
the angle of reflection is equal to the angle of incidence
light striking a rough surface is scattered in all directions

Answer 1

Answer
The angle of reflection is equal to theangle of incidence.
The law of reflection states that whenlight falls upon a plane surface it is so reflected that the angle of
reflection is equal to the angle of incidence. This happens when the incident
ray, reflected ray and normal ray all lie in the plane of incidence.
