Question 1.37 sixth edition

[Heesu_Kim_1F]

1.37) Protons and neutrons have nearly the same mass. How different are their wavelengths? Calculate the wavelength of each particle when traveling at 2.75 x 10^5 ms^-1 in a particle accelerator and report the difference as a percentage of the wavelength of the neutron.
I was able to solve the wavelength of each particle, but I am not understanding the second part of the question. What does it mean to report the difference as a percentage of the wavelength of the neutron, and how do I do this?
Thank you in advance!

Hi,

Take the absolute the difference of the two wavelengths, so subtract the wavelength of the neutron from the wavelength of the proton, and divide that number by the wavelength of the neutron. If I recall, the difference between the two wavelengths was insignificant, so the percentage should be zero.
