In an Experiment Different Wavelengths of Light, All Able to Eject

Multiple Choice

In an experiment different wavelengths of light, all able to eject photoelectrons, shine on a freshly prepared (oxide-free) zinc surface. Which statement is true?

A) The number of photoelectrons emitted per second is independent of the intensity of the light for all the different wavelengths.
B) The number of photoelectrons emitted per second is directly proportional to the frequency for all the different wavelengths.
C) The maximum kinetic energy of the photoelectrons emitted is directly proportional to the frequency for each wavelength present.
D) The maximum kinetic energy of the photoelectrons has a linear relationship with the frequency for each wavelength present.
E) The maximum kinetic energy of the photoelectrons is proportional to the intensity of the light and independent of the frequency.
