What is the photoelectric effect?
Correct Answer: Photoelectric effect
- Step 1: Understand that light is made of tiny particles called photons.
- Step 2: Know that metals have electrons that can move around.
- Step 3: When light hits the metal, if the light has enough energy (frequency), it can knock out electrons from the metal.
- Step 4: This process of electrons being knocked out is called the photoelectric effect.
