Hey !
The properties of electromagnetic waves are similar to other waves as it carries both energy and momentum due to which it exerts radiation pressure. A tiny ball can be suspended freely in a transparent vacuum chamber by shinning a laser beam on it as electromagnetic waves exerts radiation pressure.
Also, according to him, the tails of the comets are due to radiation pressure.
GOOD LUCK !!
