Light is the natural agent that simulates sight and makes the things visible. Light is also known as visible electromagnetic radiation as it is capable of causing a visual sensation and its wavelength varies from 380 nanometers to 780 nanometers.Characteristics of LightThe main characteristics of light are given as follows −Light is nothing but a form of energy produced by a luminous object.It is an electromagnetic radiation, thus it can travel through vacuum.In an optically homogeneous medium, light travels in a straight line.When light falls on a polished surface such as mirror or metal surface, it bounces back. This bouncing ... Read More
