Calculate the total energy in kj absorbed by a person, Ask an Expert

Academics

The UV light responsible for tanning skin has an average wavelength of 360 nm. Calculate the total energy (in kJ) absorbed by a person exposed to this radiation for 2.0 hours, given that there are 2.0 x 10^16 photons hitting earth's surface per square centimeter per second and the exposed body area is 0.38 m^2. You can assume that half of the energy is absorbed by the body and the other half is reflected.
