My question is how do I solve this:
Find the de Broglie wavelength of a 1500kg car when its speed is 80km/h. How significant are the wave properties of this car likely to be?
Demonstrate that the Planck distribution reduces to the Rayleigh–Jeans law at long wavelengths.
Suppose a two-slit interference experiment is carried out using an electron beam. Would the same interference pattern result if one slit at a time is uncovered instead of both at once? If not, why not? Doesn’t each electron go through one slit or the other? Or does every electron go through both slits? Discuss the latter possibility in light of the principle of complementarity
