Problem

The wave nature of matter was a major prediction of quantum theory. (i) State the hypothesis that relates the wavelength of a material particle to a mechanical property of that particle. (ii) Using this hypothesis, explain qualitatively why wave effects such as diffraction are easily observed for electrons but are practically impossible to detect for objects like a football. (iii) Describe any two experimental conditions that must be satisfied in order to observe interference or diffraction of matter waves for sub-atomic particles.
