A UV photon can break chemical bonds, but an IR photon can only cause vibration in the bonds. Calculate the energy associated with these processes by assuming a wavelength of 320 nm for the UV photon and a wavelength of 5000 nm for the IR photon.

I got....

UV photon: E = 6.22 x 10-19Joules

IR photon: E = 3.98 x 10-20Joules

Thanks!

Thanks, ehild! I wasn't sure I remembered how to do those correctly.
