WebExample: Let's calculate the energy of a single photon of red light with a wavelength of 700.0 nm and the energy of a mole of these photons. Red light with a wavelength of 700.0 nm has a frequency of 4.283 x 10 14 s-1. Substituting this frequency into the Planck-Einstein equation gives the following result. Web11 jul. 1997 · An Einstein of green light has an energy of about 200 kJ. Every day you use up the equivalent of more than 20 moles of green light. Because biological systems that capture light energy are imperfect, many more moles of photons must illuminate plant leaves before they can store the amount of energy you need every day. WebThis is the energy for one photon.
