Consider a proton moving with a speed of 7.0 × 103 m/s.
a) Calculate the de Broglie wavelength of this proton.
Consider an electron having a de Broglie wavelength that matchesthat of the proton found in part a).
b) Calculate the speed of this electron.
c) Consider an electron and a proton with precisely the samemomentum.
How do their de Broglie wavelength’s compare?
