Question

A light of frequency 'v' is incident on the metal surface whose threshold frequency is 'v₀'. If v = v₀, then [c = speed of light in medium] ____________.

Options

• the photoelectric effect is possible

• emitted electrons will move with speed less than c

• the photoelectric effect is not possible

• emitted. electrons will move with speed of light, c

Answer 1

A light of frequency 'v' is incident on the metal surface whose threshold frequency is 'v₀'. If v = v₀, then the photoelectric effect is possible.
