Question

What is the photoelectric effect ? ​

Answer 1

The photoelectric effect is the emission of electrons when electromagnetic radiation, such as light, hits a material. Electrons emitted in this manner are called photoelectrons

Answer 2

The photoelectric effect is a phenomenon where light (or other forms of electromagnetic radiation) shining on a material can make it emit electrons. Basically, light can kick out tiny particles called electrons from the surface of certain materials, and this helps us understand how light and matter interact. It's like how a soccer ball hitting a wall can make a smaller ball fall off the wall.
