Question
Among the following travelling objects, which has the shortest de Broglie
wavelength?
Hint: It is not necessary to calculate the wavelength for each object. The quickest
way to answer this question is to consider how the de Broglie wavelength depends
on the momentum (mass x speed).
A Neon atom (mass 3.4×10-26 kg) traveling at a speed of 3×10³ m/s
A person of mass 80 kg running at a speed of 3 m/s
A bird of mass 2x10-2 kg flying at a speed of 10 m/s
A Boeing 777 airplane (mass 2.5x105 kg) flying at a speed of 250 m/s (560 mph)
A car of mass 2x103 kg driving at a speed of 50 m/s
