Question

Why cannot we see the path of light in a dust free room??????????

Answer 1

HEY MATE...!!

HERE IS YOUR ANSWER:

This happens due to the scattering phenomenon of light by dust particles. Light travels in a straight line path. This principle is called as the Rectilinear Propagation of light. But some objects, like here the small dust particles can come in the path of light and scatter it. Then the path of light is deviated from its straight line path and, as a result of this the dust particles become visible.


HOPE IT HELPS....!!
