Let's think more about de Broglie's relation. Macro scale matters have wave nature, i.e., wavelength? (1) Our (humans) movements also have wavelength? Calculate wavelength of a human with a speed of 1 m/s. (2) How about electrons whose mass is extremely light? Calculate wavelength of an electron with a speed of 1 m/s.
