Many general properties of light were known to the Greeks and later on, the scholars of the Islamic civilization perfected the knowledge of light and its associated phenomena. It was considered as rays or pencil of rays whenever one described a parallel beam of light. Light falling on objects, is redirected in another direction. We may call it reflected light. But, the most general word for the redirected light bouncing off from an object is called Scattering of light.

Known to the Muslim Scholars in the middle ages. Reflection and Refraction Light falling on a mirror is reflected, is a common phenomenon. A ray of light falling on a plane mirror is reflected such that the angle of incidence is equal to the angle of reflection. Also, the incident ray, the reflected ray and the normal drawn at the point of incidence lie in one and the same plane. A ray of light falling at an interface of two media such as air and water, divides into two parts.
