Determine the de Brogile wavelength of (a) an electron moving at a speed of 6.0X 10^6 m/s (b) a baseball (mass=0.15kg) moving at a speed of 13m/s. Please provide the calculation steps by steps . Thank you very much!!
最佳解答:
de Brogile wavelength λ = h/(mv) where h = Planck's constant = 6.63 x 10-34 Js (a) Mass of an electron = 9.1 x 10-31 kg λ = 6.63 x 10-34/(9.1 x 10-31 x 6 x 106) = 1.214 x 10-10 m (b) λ = 6.63 x 10-34/(0.15 x 13) = 3.4 x 10-34 m
