Which Laser Beam Carries More Energy Per Photon – A Red Beam Or A Green Beam?
Hi! To calculate the energy of photon,you use the formula : E=hf. (where E=energy of photon,h=Planck constant,f=frequency of photon) Since h is a constant,the determining variable will be the frequency.Since green light has a higher frequency (due to shorter wavelength), green beam carries more energy per photon!
