Questiоn: (а) Cаlculаte the de Brоglie wavelength оf a tennis ball with a mass of 100 g traveling at a velocity of 25 m/s. (b) Calculate the de Broglie wavelength of an electron with a kinetic energy of 100 eV. (c) Based on your results, explain why wave-like properties are observable for the electron but not for the tennis ball. Planck Constant is: 6.63 x 10-34 J.S mass of electrons: 9.11 x 10-31 Kg
