Hint:Before proceeding to the question let us first know the basics of the topic.The photoelectric effect and the Compton effect are two types of light-matter interactions. Both effects reveal electromagnetic waves' particle nature.
Complete answer:
In the photoelectric effect, a single electron absorbs the entire energy of an incident photon, but in the Compton effect, the incident photon only transfers a portion of its energy to one electron. The photoelectric effect is a low-energy phenomena, and the photons that interact with electrons vanish as soon as they give their energy to them.
The Compton effect, on the other hand, is a mid-energy phenomenon in which photons contact electrons and are scattered. The primary distinction between the Photoelectric Effect and the Compton Effect is this.With the help of a table, we can better grasp the differences between the photoelectric and Compton effects.
The differences between photoelectric effect and the Compton effect are:
Note:Because the photon interacts with a free electron in Compton scattering, it cannot absorb the complete energy of the photon, as it does in the photo-electric effect, because momentum conservation is violated.

The differences between photoelectric effect and the Compton effect are:
Photoelectric effect | Compton effect |
1. Albert Einstein explained the photoelectric effect | 1. Arthur Compton explained the Compton effect |
2. The photon transfers all of its energy to a single electron. | 2. A portion of the photon's energy is transferred to a single electron. |
3. A low-energy phenomenon is the photoelectric effect. | 3. The Compton effect is a phenomenon that occurs at a mid-energy level. |
4. After the interaction, the photon vanishes. | 4. The dispersed photon has a longer wavelength than the incident photon. |
Note:Because the photon interacts with a free electron in Compton scattering, it cannot absorb the complete energy of the photon, as it does in the photo-electric effect, because momentum conservation is violated.
