An electron and a proton<br />
have the same speed.<br />
Which has the longer<br />
wavelength?<br />
Wave-Particle Duality II<br />
1) electron<br />
2) proton<br />
3) both the same<br />
4) neither has a wavelength<br />
Remember that<br />
λ<br />
= h<br />
mv<br />
and the particles both<br />
have the same velocity, so the particle with the<br />
smaller mass will have the longer wavelength.
