What is the de 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, and (c) a dust particle of mass 1.0 × 10-9 kg drifting with a speed of 2.2 m/s?
(a) λ=mvh=0.04×10006.62×10−34=1.655×10−35m (b) λ=mvh=0.06×16.62×10−34=1.1×10−32m (c) λ=mvh=1×10−9×2.26.62×10−34=3×10−23m
