Answer to Problem 1Q

The light is behave as both particle and wave nature.

Explanation of Solution

Experimental evidence shows that light can acts as both a wave and a particle that means dual nature of light. The theory evolved from electromagnetic into quantum mechanics. Einstein believed light as a particle and the flow of photon is a wave.

Experiments such as young’s double slit interference and the Michelson interferometer shows that light can acts as a wave.

Experiments such as Einstein photoelectric effect shows that light can behave like a particle called a photon with discrete energy.

Conclusion:

Therefore, the light is behave as both particle and wave nature.
