Propagation of light refers to the manner in which light energy moves from one point to another. When an electric lamp is switched on, the lamp is seen from all sides. Light is observed to be sent out from the lamp in all directions.

Rectilinear propagation of light
The property of light travelling in a straight line is known as the rectilinear propagation of light. A light source can be seen if there is a straight line path between the source and our eyes. This can be demonstrated by following experiment.
