Light reflection is a common phenomenon that we can observe in our daily lives. When light hits a smooth surface, it bounces back. This is called reflection. For example, we can see our reflection in a mirror. The mirror is a smooth surface that reflects light very well. ...
Depending on the type of surface the light rays will be reflected differently. The simplest example of this is light reflecting off a mirror. The polished surface of the mirror perfectly reflects any light bouncing off of it. This is known as specular reflection. Fig. 1: Diagram showing ...
