ConcepTest <strong>27</strong>.3a<br />

The speed of proton A is<br />

larger than the speed of<br />

proton B. Which one has<br />

the longer wavelength?<br />

Wave-Particle Duality I<br />

1) proton A<br />

2) proton B<br />

3) both the same<br />

4) neither has a wavelength<br />

Remember that<br />

λ = h<br />

mv<br />

so the proton with the<br />

smaller velocity will have the longer wavelength.
