E = h*nu, or E = h*c/lambda where E is the photon energy h = Plank's constant nu is the frequency lambda is wavelength. In SI units, h is expressed in joules, although it is also commonly expressed in electron volts. Infrared radiation of approximately 1240 nm has an energy of 1 electron volt. 3 electron volts corresponds to blue light of 413 nm, and 4 eV is getting to be nasty UV of 310 nm. 5 eV will break O2 bonds and form ozone.

Multiply the frequency of the photon by Planck's constant.
