B. Light is very predictable and it follows a general set of rules for its behavior. The incident ray is the ray of light that is hitting an object. From that spot, a perpendicular line is drawn. This is known as the normal line. A ray is a line with an endpoint.

In terms of light, the endpoint would be the starting spot from the sun or other light source. The angle between these two, the incident ray and the normal line, would be considered the angle of incidence. The light that leaves the object would be called the reflected ray.
