If Photons Have No Mass, How Can They Have Momentum ...
WebDetermine the energy of one mole of photons at the wavelength of maximum emission. *find the highest point and use that wavelengh for the equation (E total= E (Joules/Photons x 6.02x10^23) E2: How do you find the maximum frequency? The highest frequency corresponds to the lowest wavelenth measured. WebThe energy of a photon can be calculated from Planck's equation, by multiplying the photon frequency by Planck's constant. Due to the property of photons which relates wavelength to frequency by the constant speed of light, we can set up a simple photon energy calculator in the form of an equation. pro tools mp9 mac os
