The de Broglie equation predicts that the wavelength (in m)of a proton moving at 1000.m/s is ________________.(h = 6.63 × 10^-34 J • s; mass of a proton = 1.673 × 10^-24 g) A)3.96 × 10^-1⁰ m B)3.96 × 10^-7 m C)2.52 × 10⁶ m D)2.52 × 10⁹ m E)> 10¹⁰ m

Quizplus · Accepted Answer

The de Broglie wavelength is calculated using λ = h / (mv). Converting the mass of the proton to kg (1.673 × 10^-27 kg) and using the given velocity, λ = 6.63 × 10^-34 / (1.673 × 10^-27 * 1000) = 3.96 × 10^-10 m.
