A typical gamma ray emitted from a nucleus during radioactive decay may have an energy of 736 keV. What is its wavelength?


A microwave oven produces electromagnetic radiation at λ = 12.1 cm and produces a power of 778 W. Calculate the number of microwave photons produced by the microwave oven each second

    Gamma rays travel at the speed of light, 3*10^8 m/s. You can get the frequency f from the Planck relation
    E = h*f
    h is Planck's constant.
    Get to know it.

    Convert 736,000 eV to Joules.
    1 eV = 1.6*10^-19 J
    E = 736 keV = 1.18*10^-13 J
    f = E/h = ___
    wavelength = c/f = _____
