A scientist shines light with energy greater than the binding energy of platinum on a thin film of it.The same scientist then repeats the experiment with a higher intensity light.According to the photoelectric effect,what should be observed?
A) No electrons are ejected in either experiment.
B) Electrons are not ejected in the first experiment, but are in the second.
C) Electrons are ejected in both experiments, but the first experiment takes longer to eject electrons than the second.
D) Electrons are ejected in both experiments at the exact same time.
E) Electrons are ejected in both experiments, but the second experiment takes longer to eject electrons than the first.

The photoelectric effect states that electrons are ejected when light with energy greater than the binding energy is shone on a material. Increasing the intensity increases the number of electrons ejected but does not affect the time of ejection.
