Question

what was de Broglie's experiment

Answer 1

HEY MATE HERE IS YOUR ANSWER

Before the acceptance of the de Broglie hypothesis, diffraction was a property that was thought to be exhibited only by waves. ... Just as the photoelectric effect demonstrated the particle nature of light, the Davisson–Germer experiment showed the wave-nature of matter, and completed the theory of wave–particle duality.

Answer 2

The validity of de Brogile's proposal was confirmed by electron diffraction of G.P Thomson in 1926 and C. Davisson and L.H Germer in 1927. In these experiment it was found that electrons were scattered from atoms in a crystal and that these scattered electron produced an interference pattern.
