Rachel Maddiee Posted December 27, 2019 Share Posted December 27, 2019 The de Broglie equation relates to the wave property of matter. λ = h/mv, where λ is wavelength, h is Planck's constant, m is the mass of a particle, moving at a velocity v. h = 6.626 x 10^-34 J•s. m = 96.0 mg v = 30.0 m/s Convert milligrams to kilograms m = 96.0 mg x 1g/1000 mg x 1kg/1000g = 9.60 x 10^-5 kg Calculate the wavelength λ = 6.626 x 10^-34/96.0 x 10^-5 x 30.0 = 2.30 x 10^-31 m Is this right?
