A person does not apply sunscreen and has 0.42 m2 of skin exposed to the sun for 1.00 h. Calculate the total energy (in joules) absorbed by the skin. Assume there are 3.066×1021 photons/(m2⋅s) (photo

ns per square meter-second). Assume an average wavelength of 320 nm to calculate the energy of a UV photon. Assume that half of the photons that strike the skin are reflected.
