### 1B.19

I know we didn't have to end up reporting the difference as a percentage of the wavelength of the neutron because the wavelengths were the same at 3 significant figures, but if we did, how would we go about doing that?

The answer for this question just ends up being that the wavelength of a proton and a neutron are identical to 3 significant figures. The solutions guide doesn't actually end calculating the final answer as a percentage of either the proton/neutron's weight. You just have to use the equation to find the wavelength of both particles and the answers are nearly identical to 3 significant figures.
