Homework Help: Photoelectric Effect True/False

  1. Apr 11, 2010 #1
    1. The problem statement, all variables and given/known data
    Which of the following statements about the photoelectric effect are true?


    -(T/F) The number of emitted electrons depends on the frequency, not the number of photons.
    -(T/F) The radiation needs a minimum number of photons for any electrons to be released.
    -(T/F) The energy of the radiation is inversely proportional to the wavelength.
    -(T/F) The kinetic energy of emitted electrons depends on the frequency, not the number of photons.


    please help. Thanks!!


    2. Relevant equations



    3. The attempt at a solution
    my first two tries were (F,F,F,T) and (T,F,F,T). both wrong of course
