3:42 .ull 5G Done 2 of 2 John Isner holds the ATP's (Association of Tennis Professionals) official record for the fastest serve at 253 km/h. Calculate the de Broglie wavelength of a tennis ball with the standard weight of 54.6 grams. Give your answer in 1034 m (for example, if your answer is 5.6x1034 m, then enter 5.6). This should give you a good idea of why one cannot expect to observe interference affects using tennis balls rather then, for example, electrons. +)
