In the photoelectric effect, increasing the intensity of light above the threshold frequency increases which quantity?

Answer and explanation

Correct answer: D. The number of emitted electrons

  1. Step 1: More intense light delivers more photons, so more electrons are emitted.
  2. Step 2: The maximum kinetic energy depends on frequency.
Answer
The number of emitted electrons.
Why not the others: The kinetic energy, threshold frequency and work function do not depend on intensity.
