Discover the Photon Energy of Green Light: Solving the 522nm Wavelength Problem

[McMaster_Girl]

What is the energy carried by a mole of photons of wavelength 522nm which is associated with green light?

 

[Repetit]

Find the energy carried by one photon and multiply by Avogadro's number.

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

$$E=h \nu$$

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

The energy of a photon is given by the equation E=hc/λ, where h is Planck's constant, c is the speed of light, and λ is the wavelength of the photon. Substituting the given wavelength of 522nm into the equation, we can calculate the energy of a single photon of green light to be approximately 2.38 x 10^-19 joules.

To determine the energy carried by a mole of photons, we can use Avogadro's number (6.022 x 10^23 photons/mol) and multiply it by the energy of a single photon. This gives us an energy of approximately 1.43 x 10^5 joules/mol.

This energy value represents the amount of energy carried by a mole of photons of wavelength 522nm, which is associated with green light. It is important to note that this value may vary slightly depending on the specific wavelength of green light being considered, as well as other factors such as atmospheric conditions.

Overall, understanding the energy carried by photons is crucial in understanding the behavior and properties of light, and this calculation provides valuable insight into the energy of green light and its impact on our world.
