About Photoelectric effect :

• When a substance absorbs electromagnetic radiation, electrical charges particles are emitted from or inside it, causing the photoelectric effect. The emission of protons from a steel plate while light falls on it is a common definition of the effect.

• The photoelectric effect, also known as photoelectric absorption, is one of the most common ways for x-ray and gamma photons to interact with materials.

• Whenever electromagnetic waves, such as light, strikes a substance, it causes electrons to be emitted.
