Protons and neutrons have nearly the same mass. How different are their wavelengths? Calculate the wavelength of each particle when traveling.....

I've been using DeBroglie's eqn. for this, but I'm not getting the right answer? Could someone post their work? thank you!

[Alexis Webb 2B]

if you plug it into your calculator exactly like this, you should get these answers. Using the de Broglie equation is the correct approach and the two answers should be the same to three sig figs.

Because they have about the same mass, they should have pretty much the same wavelength

Will we be given the mass of the proton/neutron on the formula sheet? Or are we expected to know it?
