How does light act like a particle?

Solution

1. Despite the fact that light primarily exhibits wave-like behavior, it can also be said to be made up of tiny energy packets known as photons.

2. Although they lack mass, photons have a constant quantity of energy. A photon's energy varies with its wavelength; those with longer wavelengths have less energy than those with shorter ones.

For instance, red photons are less energetic than blue ones.

3. Although it often behaves like a wave, photons, which are small bundles of energy, are also thought to make up light. Although they lack mass, photons have a constant quantity of energy.

4. The photoelectric effect, also known as photoemission, is the process by which a metal surface emits free electrons when exposed to light.

5. The photoelectric effect, also known as photoemission, is the emission of free electrons from a metal surface when light is shone on it. This result led scientists to the conclusion that light is composed of energy packets or quantum. The issue at hand was whether the light quantum theory indicated that light was a particle or not. Einstein already connected momentum and the light quantum. This provided compelling evidence that light is made up of tiny particles known as photons. The wave-particle duality of light was thus introduced.

This result led scientists to the conclusion that light is composed of energy packets or quantum. The particle nature of light is strongly supported by this phenomenon.
