SUMMARY

The energy of a mole of photons at a wavelength of 522nm, corresponding to green light, can be calculated using the formula E=hν, where h is Planck's constant. To find the energy of one photon, the frequency must first be derived from the wavelength using the equation ν=c/λ, with c representing the speed of light. After determining the energy of a single photon, multiplying by Avogadro's number provides the total energy for a mole of photons.

PREREQUISITES
  • Understanding of Planck's constant (h)
  • Knowledge of the speed of light (c)

What is the energy carried by a mole of photons of wavelength 522nm which is associated with green light?
 
Physics news on Phys.org
Find the energy carried by one photon and multiply by Avogadro's number.

In terms of frequency the energy carried by a photon is:

<br /> E=h \nu<br />

Where h is Planck's constant and \nu is the frequency. So you have to express the frequency through the wavelength.
