Q:3)(20) A spaceship traveling at 0.66c away from Earth fires a module with a speed of 0.82c at right angel to its own direction of travel (as seen by the spaceship). What is the speed of the module, and its direction of travel (relative to the spaceship's direction), as seen by an observer on Earth? Q:4)(25) In a double-slit experiment with electrons, the slit separation of the apparatus d=0.1 mm and the slit-screen separation D=20 cm. We want to be able to detect the distance between two adjacent maxima on the screen, ym+1 - Ym = 1 µm. (h=6.6x103ª kg.m²/s, m-9x10³' kg) a) Find de Broglie wavelength of the electrons. b) What should be the speed of the electrons that are directed into a double-slit? c) Do we need a relativistic correction? Explain your reasoning.
