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

question 23

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.
