The energy of a mole of photons of light in the electromagnetic spectrum decreases logarithmically as a function of increasing wavelength. In the visible range, light has between 40 and 80 kcal/mole of photon energy. Below about 400 nm wavelength, the energy increases significantly. Use what you know about the energy of chemical bonds to make an argument in favor of using sun screen with UV-block on a sunny day.

A laser pulse with wavelength 515 nm contains 4.40 mJ of energy. Question: How many photons are in the laser pulse? Can someone please walk me through the steps? I have tried to solve this multiple times, but the 2 answers I thought were for sure it are A: 2.21 x 10^22 photon B: 4.40 Joules X (1 photon/3.860x10^-19 Joules) They were both wrong.
