WebDec 15, 2024 · Calculate the Energy of a Photon. We can calculate the energy of a photon in two ways. If you already know the frequency, f , of the photon in Hz, then use: E=hf E = hf. This equation was first suggested by Max Planck, who theorized that photon energy is quantized. Therefore, sometimes this energy equation is referred to as … WebQuestion 1: Visible light has wavelengths in the range of 400 nm to 780 nm. Calculate the range of energy of the photons of visible light. Solution: We know, Energy of photon = hv = hc/λ where h is plank’s constant ν is the frequency c is the speed of light and λ is the wavelength. Now,
WebNow let's see what two equations can be used to solve for the energy of a photon. The first is frequency. E = hf E = h f. Where E E is the energy, h h is Planck's constant and f f is the frequency ... WebSep 12, 2024 · Once excited, the electron “de-excites” in two ways. The electron can drop back to the ground state, emitting a photon of the same energy that excited it, or it can drop in a series of smaller steps, emitting several low-energy photons. Some of these photons may be in the visible range.
WebApr 12, 2024 · The conversion of solar energy into renewable H2 fuel via photoelectrochemical and photocatalytic water splitting approaches has attracted considerable attention due to its potential to solve significant energy and environmental issues. To achieve reasonable energy conversion efficiency of 10%, which is amenable …
