Question:
According to de Broglie, the 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.
Solution:
m= 100g or 0.1kg
ν= 100km/h =100*1000/60*60 = 1000/36m/s
λ =h/mν = 2.387*10-34m
