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/s. Calculate the wavelength of the ball and explain why it does not show wave nature.
