Questions & Step-by-Step Solutions

What is the phenomenon called when electrons are emitted from a metal surface when it is exposed to light?
  • Step 1: Understand that metals can release tiny particles called electrons.
  • Step 2: Learn that when light shines on a metal surface, it can give energy to these electrons.
  • Step 3: Realize that if the light has enough energy, it can cause the electrons to leave the metal surface.
  • Step 4: Know that this process of electrons being emitted due to light is called the photoelectric effect.
