    Electromagnetic waves, with frequencies ranging from 4.00 x 10^14 Hz to 9.00 x 10^16 Hz, are incident on an aluminium is 4.28 eV, find (a) the maximum kinetic energy of electrons ejected from this surface and (b) the range of frequencies for which no electrons are ejected.

    Please work this problem out. I don't understand how the author arrives at these numbers.

    A) 369eV
    B) 4.00 X 10^14 Hz
    1.03 X 10^15 Hz.
