... effect) De Broglie proposed that particles also have wave properties and so they actually exhibit a dual nature of both particles and wave. Since he knew that the wavelength of a photon of momentum p is given by, λ = h/p (e.g, see question 4 of assignment 1), drawing an analogy with it, he proposed ...
