What is the Broglie wavelength of
(a) a bullet of mass 0.040 kg travelling at the speed of 1.0 km/s ?
(b) a ball of mass 0.060 kg moving at a speed of 1.0 m/s ?
(c) a dust particle of mass `1.0 xx10^(-9)` kg drifting with a speed of 2.2m/s ?

Explanation

To find the de Broglie wavelength for each of the given scenarios, we can use the de Broglie wavelength formula:

\[ \lambda = \frac{h}{mv} \]

where:
- \(\lambda\) is the de Broglie wavelength,
