Question

Quizplus · Accepted Answer

The de Broglie wavelength λ of a particle is given by λ = h/p, where h is Planck's constant (6.626 × 10^-34 Js) and p is the momentum. The momentum p can be found using p = √(2mE), where m is the mass and E is the kinetic energy. Substituting the given values, the wavelength is approximately 1.8 × 10^-10 m.
