I just really need help on what formula and the steps I need to get the answer. If you give the answer then I could use it to check my answer. I would appreciate the help alot.

'UV photons are capable of breaking chemicals bonds, while IR photons can cause only vibration in a bond. SHOW YOUR WORK.

-Calculate the energy associated with an UV photon at 320nm.

-Calculate the energy associated with an IR photon at 5000nm.

-Calculate the ratio of the energy that breaks bonds to the energy that causes vibration.'
