a) In a double-slit experiment, a stream of electrons with speed v = 10 m/s is aimed at two parallel slits. On the screen one meter behind the slits an interference pattern is observed in the number of electrons arriving at different points on the screen. The distance between the first and the second intensity maxima is 1 cm. Find the distance between the slits. b) What is the distance between the first and the second maxima in the interference pattern, if we perform the double-slit experiment with footballs (mass 0,4 kg) moving at speed 10 m/s? Let's assume the slits are 1 m apart, and the screen is 10 m behind the slits. Is it possible to observe interference of footballs?
