Question

What happens if photon energy is greater than the work function?

विकल्प

• The photon becomes electrically charged.

• No electron is emitted.

• The electron is emitted with kinetic energy.

• The electron moves with the speed of light in vacuum.

Answer 1

If photon energy is greater than the work function, the electron is emitted. The energy remaining after overcoming the work function becomes kinetic energy.
