### Question on applications of the equation

Does the DeBroglie equation only work on electrons or can it also be applied to photons?

### Re: Question on applications of the equation

The equation most likely would not be applied to photons, since they do not have a mass or momentum.

### Re: Question on applications of the equation

The DeBroglie equation doesn't apply to photons because, like what the previous poster said, they do not have a measurable mass.

It applies to any particles with a mass - not just electrons! One homework problem in 1B asked for the wavelength of a proton and neutron using the equation.
