  • What is the de Broglie wavelength of (c) a dust particle of mass 1.0 × 10^–9 kg drifting with a speed of 2.2 m/s?

Q: 11.15 (c) What is the de Broglie wavelength of a dust particle of mass  1.0\times 10^-^9\hspace{1mm}kg  drifting with a speed of  2.2\hspace{1mm}m/s ?

The momentum of the dust particle is

\\p=mv\\ p=10^{-9}\times 2.2\\ p=2.2\times 10^{-9} kg\ m\ s^{-1}

De Broglie wavelength is

\\\lambda =\frac{h}{p}\\ \lambda =\frac{6.62\times 10^{-34}}{2.2\times 10^{-9} }\\ \lambda =3.01\times 10^{-25}\ m
