### Energy per photon equation

Just to clarify, in the equation: E=hv
as well as in the photoelectric experiment, the energy of per photon is reliant solely on the frequency?

### Re: Energy per photon equation

Yes energy of each light photon is dependent on the frequency of the wave.

### Re: Energy per photon equation

yes, because in the equation E=hv, h is a constant. So as the frequency increases, the energy too should increase as well

### Re: Energy per photon equation

I agree with the other students who have responded; in the equation E = hv, we learned that h is Planck's constant, equal to 6.626 x 10^-34 Js. Thus if you replace that into the equation to solve for the energy of the photon, you are left with E = (6.626 x 10^-34 Js) (v), leaving frequency of the way to be the only variable left to affect the energy. As Jamie said, I agree that if the frequency of the wave increases, then the energy of the photon increases as well!
