Wave-Particle Duality problem 10

An effect that provides evidence for the wave nature of a particle is the electron diffraction.

An effect that provides evidence for the particulate nature of electromagnetic radiation the photoelectric effect

The de Broglie wavelength is the wavelength of a wave associated with a particle that is moving. It is given by the equation:

where is the de Broglie wavelength, is Planck's constant and is the momentum of the particle.

The speed of an electron having a de Broglie wavelength equal to the wavelength is .
