What to Focus On

  • Photoelectric effect means emission of electrons from metals due to light.
  • Photoelectrons are the emitted electrons.
  • Photoelectric current is the current produced by these electrons.

  • P1 is the cathode plate placed in front of the quartz window.
  • P2 acts as the collector or anode.
  • Positive potential on P2 gives saturation current.

  • Photoelectric current is directly proportional to intensity.
  • Stopping potential does not depend on intensity.
  • Maximum kinetic energy does not depend on intensity.

Common Mistakes to Avoid

Increasing the intensity of light always increases the maximum kinetic energy of photoelectrons.

Photoelectric current and maximum kinetic energy depend on the same factor, so if current increases, kinetic energy must also increase.

There is a threshold intensity below which no photoelectric effect occurs.
