A pro tennis playerâs serve can reach speeds of more than 100 mph. Compare the de Broglie wavelength of an electron moving with a velocity of 5.0 x 10^6 m/s with that of a tennis ball traveling at 56.0 m/s.
Mass of e-= 9.11 x 10^-31kg
Mass of tennis ball = 0.0567 kg
h= 6.626 x 10^-34 J·s and 1 J = 1kg·m^2 s^-2
