Quantized Energy and Photons (Section)
One type of sunburn occurs on exposure to UV light of wavelength in the vicinity of 325 nm.
(a) What is the energy of a photon of this wavelength?
(b) What is the energy of a mole of these photons?
(c) How many photons are in a 1.00 mJ burst of this radiation?
(d) These UV photons can break chemical bonds in your skin to cause sunburn—a form of radiation damage. If the 325-nm radiation provides exactly the energy to break an average chemical bond in the skin, estimate the average energy of these bonds in kJ/mol.
