Energy of a Photon Calculate the energy of one photon of yellow light that has a wavelength of 589 nm. Which of the following expressions correctly gives the energy of a mole of photons with wavelength A?

Solution: Here, we are going to find the correct expression for the energy of a mole of photons with wavelength . Step1: According to Planck’s quantum theory of radiation, the amount of energy associated with a quantum(in case of light, the quantum of energy is often called photon) of radiation is proportional to the frequency of light, E = h , where h is a universal...
