What is the de-Broglie wavelength of (a) a bullet of mass `0.040kg` traveling at the speed of `1.0kms^(-1)`. (b) a ball of mass `0.060 kg` moving at a speed of `1.0ms^(-1)` and (c) a dust particle of mass `1.0xx10^(-9) kg` drifting with a speed of `2.2 ms^(-1)`? `h=6.63xx10^(-34)Js`.

Explanation

To find the de Broglie wavelength for each of the given objects, we will use the de Broglie wavelength formula:

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

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