Light demonstrates the characteristics of particles only waves only both particles and waves neither particles nor waves

The correct answer is "both particles and waves".

Explanation:

Light shows dual nature. Sometimes, it behaves like particle or wave.

The particle nature of the light is shown by photoelectric effect. This effect cannot be explained by the wave nature of the light.

Light consists of the packet of energy which is known as photon.

Photoelectric effect: It is the phenomenon in which there is an emission of the electrons when the light is incident of particular frequency on the surface of the metal.

The wave nature of the light is explained by reflection.

Reflection: Reflection is the phenomenon in which the light wave gets reflected from the surface without getting absorb. It bounces back from the surface.

Therefore, Light demonstrates the characteristics of  both particles and wave.

i think the answer would be reserve.
