Question

Which feature of photoelectric emission could classical wave theory not explain?

विकल्प

• The work function is the minimum energy required to remove an electron.

• Photon energy increases with frequency.

• Emission is instantaneous.

• Stopping potential is related to maximum kinetic energy.

Answer 1

Classical wave theory could not explain why emission is instantaneous. A single photon can transfer its energy to a single electron in one interaction.
