Quizplus · Accepted Answer

The de Broglie wavelength is given by λ = h/p, where h is Planck's constant and p is the momentum of the object. As momentum is directly proportional to an object's mass and velocity, the lighter the object, the larger its de Broglie wavelength for the same kinetic energy. Therefore, the electron, which has a very small mass compared to the other objects listed, will have the largest de Broglie wavelength.
