Finding photon energy from wavelength
Web717K views 5 years ago New AP & General Chemistry Video Playlist. This chemistry video tutorial explains how to calculate the energy of a photon given the frequency and the wavelength in nm. WebIn order to find the energy of the photon that was absorbed or emitted, you always take the higher energy level and subtract from it the lower energy level. So in this case, we would take -6eV, and subtract from it -10eV, which tells us that it would take a four eV photon to bump an electron up to that energy level, and the electron would emit ...
