Q33Short answer
According to de Broglie, matter should exhibit dual behaviour, that is both particle and wave like properties. However, a cricket ball of mass 100 g does not move like a wave when it is thrown by a bowler at a speed of 100 km/h. Calculate the wavelength of the ball and explain why it does not show wave nature. 19 Structure of Atom

m = 100 g = 0.1 kg. 100 1000 m 000 1 v = 100 km/hr 60 60 s h = 6.626 × 10–34 Js 34 6.626 10 Js 36 1 6.626 10 36 m = 238.5 × 10–36m–1 1000 1 0.1 kg ms Since the wavelength is very small, the wave nature cannot be detected.
