Transcribed Image Text:**Question:**
Among the following traveling 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 × speed).
**Options:**
- A Neon atom (mass \(3.4 \times 10^{-26}\) kg) traveling at a speed of \(3 \times 10^3\) m/s
- A person of mass 80 kg running at a speed of 3 m/s
- A bird of mass \(2 \times 10^{-2}\) kg flying at a speed of 10 m/s
- A Boeing 777 airplane (mass \(2.5 \times 10^5\) kg) flying at a speed of 250 m/s (560 mph)
- A car of mass \(2 \times 10^3\) kg driving at a speed of 50 m/s
