Laurence Lavelle Skip to content. This equation states that the frequency and energy of a quantum of electromagnetic radiation are proportional. So, in order to emit 60 Joules per second, the lightbulb must emit 1. Now, by using an indirect method, scientists have finally made this measurement. Of course these photons are spread out over the area irradiated but there are still many, many photons per unit area.

Hence option b is the correct answer. According to Photon Energy Calculator a green photon wavelength nm has an energy of about 2. Converting to Joules gives 3. There are 1. Begin typing your search term above and press enter to search. Add a comment. Active Oldest Votes.
