What determines the number of electrons ejected when a beam of light is shone on a metal surface?

Options

  1. AThe color of the light
  2. BThe velocity of the electrons
  3. CThe intensity of the light
  4. DThe number of photons in the beam

Correct answer

D. The number of photons in the beam

Step-by-step solution

A more intense beam of light, consisting of a larger number of photons, results in a larger number of electrons being ejected compared to a beam of weaker intensity of light.
