Question

name a phenomenon which illustrates ​

Answer 1

Answer:

Photoelectric effect illustrates the particle nature of light.

Answer 2

Explanation:

photophoresis effect, or the light induced motion.

In space satellites have a reflective mirror on one side which reflects the light particle striking it, but during the process light particles push the atoms of the mirror by imparting bit of momentum each time. Since space has no friction to deal with, this tiny bits of momentum builds up and propells the satellite like the wind does to a sailing ship.

Now momentum is a property possesed by a particle having mass. Thus we can infer that light is a particle.
