A proton and an electron are both traveling at the same speed. What can we conclude about their de Broglie wavelengths?

Expert Answer:

C. The wavelength of the proton will be shorter than that of the electron
 
This is because mp > me
and since wavelength and mass are inversely proportional to each other, the wavelength of the proton will be shorter than that of the electron.
