Used for Photons Only

Postby 904914037 » Tue Oct 22, 2019 9:12 pm

Could someone please explain why E=hv can only be used for photons? Thank you!

I believe that the quantity of energy found in E=hv is just the smallest unit of energy for that particular frequency. It might help to think of the equation as E=(number of photons)*hv and, so, if your number of photons is just 1, then you're left with E=hv. You could then take that energy and multiply it by a greater number of photons to see how many Joules of energy would be in several photons rather than just one.

E=hv is the equation used to solve for the energy of a particle of light, which is a photon.

Is the "h" in the E=hv equation a constant value? Is this plank's constant?

Yes, h is Planck's constant (6.626 x 10^-34 J*s)

Will we also be provided these constant values on the midterm? Thank you.
