Exposure to high doses of microwaves can cause tissue damage. Estimate how many photons with a wavelength = 12cm, must be absorbed to raise the temperature of your eye by 3.0 deg C. Assume the mass of the eye is 11g and its specific heat is 4.0 J/gK

    How much heat energy is needed to raise the T of the eye?
    q(in joules) = mass x specific heat x delta T.

    How much energy does each photon have?
    E(in joules) = hc/wavelength

    E/photon x # photons = q
    Solve for # photons.
