Usage of Einstein Equation

Postby Riya Sood 4G » Tue Oct 22, 2019 10:33 pm

How can we use the Einstein equation E=hv to calculate the number of photons ?

The equation E=hv gives you the energy of a single photon. If you have the total energy of a source of light, you can figure out the number of photons by dividing the total energy of the light by the energy of a single photon of the light.

In addition, be careful not to mistakenly use this equation when regarding electrons, Einstein equation is only intended for photons.
