Compare the de Broglie wavelength of an alpha particle moving at
3.40\times 10^(7)
miles per hour
(1.52\times 10^(7)(m)/(s))
to that of a baseball moving at 90.0 miles per hour (
40.2(m)/(s)
) and a proton with a speed of
1.30\times 10^(7)
miles per hour (
5.81\times 10^(6)(m)/(s)
). \table[[Particle,Mass
