Question

Calculate the de Broglie wavelength of a 0.17-kg ball moving at 35 m/s. m Comment on the significance of the result. SmallCircle The de Broglie wavelength is not negligible compared with the size of the ball, so we cannot safely treat the ball as a particle. SmallCircle The de Broglie wavelength is not negligible compared with the size of the ball, so we can safely treat the ball as a particle.

Explanation / Answer

de broglie wavelength = h/P = h/mv = h/0.17*35 = 0.168h = 0.168*6.62 = 1.1121*10^-34 m

1.1121*10^-34 m <<<<< size of ball

hence option B
