A particular microwave oven operates at 1000W. The wavelength of the microwave is 12.0cm. You decide that you like your snack to absorb 1.2 x 10^28 photons. For how much time should you have the oven on- with your snack inside of course. Assume 100% efficiency.

    I guess I will answer my own question so, if others come across it, it will help

    PT/h(lamda)
    P: power
    T: time (which is the variable in this case)
    h: (constant 6.626x10^-34)
    c: lamda is found by c/f in which,
    c= 3x10^8
    frequency= .12 in this case
    if you solve accordingly,
    t= 19.8 seconds
