### de Broglie and neutrons

Can we use De Broglie's equation for neutrons?

Yes, de Broglie's equation can be used for anything that has a mass and velocity, even larger objects like basketballs!

Yes, the De Broglie equation can used for neutrons. I think it can be used for any particle with mass, you can even use it to calculate the wavelength of a moving object.

Yes, because it has a measurable mass, even if it seems really small, therefore the equation is applicable here.

Yes! De Broglie's equation is most commonly used to describe the wave nature of electrons, but can be used for any particle with mass.

### Re: de Broglie and neutrons

Yup! Here is a summary of what equations can be used for certain particles.

$E=hv$ --> only for photon
$c=\lambda v$ --> only for photon
$E=\frac{1}{2}mv^{2}$--> anything that has a mass and velocity (eg: electrons) so NO PHOTONS
$\lambda = \frac{h}{mv}$ --> anything that has a mass and velocity so again NO PHOTONS
$E=\frac{-hr}{n^{^{2}}}$ --> only for electrons (absorption and emission)

Yes, De Brogile’s equation can be used for neutrons. It can also be used for protons in addition. Since you know the mass of protons and neutrons you can use the De Brogile’s equation.

### Re: de Broglie and neutrons

The de Broglie equation can be used with anything that has mass. So it can be used on neutrons, electrons, protons, and macroscopic objects like baseballs, but it can't be used on photons since light doesn't have mass. For light you'll need to use other equations.

I apologize, so we can only use the final equation for electrons because it specifically helps us find the spectral positions of the electrons correct? And I believe we can also use the Rydberg Equation to do the same, albeit with one less step.
