    Calculating Work Function of Metal in a Photocell

    Homework Statement In a particular photocell, light with a frequency of 8×10^14Hz is directed onto the cell and it is found that a stopping potential of 1.2V is needed to reduce the photoelectric current to zero. Calculate the work function of the metal in the cell. Homework Equations...

    Calculating number of Photons absorbed by a surface

    If light with a frequency of 4.41*10^15 Hz falls on a surface that gains 1.13*10^-16 J of energy, how many photons has the surface absorbed? Probably simple, I've been using E = hf and such, but I got no idea from there Help meeee please
