Consider a beam of electromagnetic radiation of a single frequency. The energy of each photon in this beam depends on each of the following properties of the beam except one. Which is the exception

Respuesta :

Answer:

The energy of each photon does NOT depend on the intensity of the beam

Explanation:

The energy of a photon is given by Planck's relationship

         E = h f

Where h is Planck's constant and f is the frequency of electromagnetic radiation

 

The speed of light is given by the relationship

         c = λ f

We substitute in the Planck equation

         E = h c / λ

Therefore the energy of each photon depends on the radiation speed, wavelength and frequency.

The energy of each photon does NOT depend on the intensity of the beam
