In an experiment, photoelectric effect is observed in metal A when light with frequency (f ) falls on the metal. If the light frequency used in this experiment is doubled, the photoelectrons

A metal surface is struck with light of λ = 400 nm, releasing a stream of electrons. If the 400 nm light is replaced by λ= 300 nm light of the same intensity, what is the result?
