Protons and Electrons

Postby 405289292 » Mon Oct 21, 2019 9:23 pm

Would a proton and a neutron have the same velocity if they had the same wavelength?

If the protons and electrons are moving at the same velocity, it would mean that the protons have a shorter wavelength. However, if they are moving at the same momentum it would mean they have the same wavelength.

Yes, I think that if a proton and neutron had the same wavelength, they would have the same velocity. You can use De Broigle's to determine that wavelength = h/p which is the same as: wavelength = h/mv. v=h/(m*wavelength) and the mass of a proton and neutron are the same. If the wavelength is also the same, the velocity of both will be the same.

Yes, they will have the same wavelength because all the variables in the equation are the same between protons and nuetrons if they are moving at the same velocity.

Since protons and neutrons have the same mass, if they had the same velocity they would also have the same wavelength.
