उत्तर

An electron exhibits wave nature under certain conditions. Matter waves, de Broglie waves, and Schrodinger waves are all names for waves associated with a moving electron. The de Broglie wavelength of these matter waves is given by λ = h/p, where h is Planck's constant, and p is the magnitude of the electron's momentum.

When an electron is at rest, its momentum is zero, and the corresponding de Broglie wavelength is infinite, indicating that there is no matter wave. This, however, is not possible according to quantum mechanics/wave mechanics.
