How is light reflected? micro-lesson

How is light reflected? Reflection is when light bounces off the surface changing the direction of a ray of light. Now, all objects do reflect light, but smooth and shiny surfaces reflect all rays of light at the same angle. Rough or dull surfaces will scatter the rays of light. The light ray that hits a mirror or another reflective object is called the incident ray, the ray that comes from the light source, and the rate that bounces off is known as the reflective ray, the light that's being reflected. The Law of Reflection says that the angle of incidence must always be equal to the angle of reflection. So, if a light ray hits the mirror at 45 degrees, it will be reflected at 45 degrees. Now, looking at this diagram, that thick black line is called the normal ray and that's drawn perpendicular to the reflective surface. So, the Law of Reflection will say that the angle of incidence, which is the angle between the incident rate and the normal line, must be the same as the angle of reflection, that angle between the normal line and the reflected ray.
