(N/A) The wavelength of light is very small compared to the size of ordinary objects. Due to this,light travels from one point to another along a straight line path. This phenomenon is known as the rectilinear propagation of light.
$A$ ray of light is defined as a line representing the path along which light energy travels. It is represented by a straight line with an arrowhead indicating the direction of propagation.
$A$ beam of light is a bundle or collection of a large number of light rays traveling together in a particular direction.

What is rectilinear propagation of light? Explain ray of light and beam of light.
