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 w avelength of the ball and explain why it does not show wave nature.

1.	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 w avelength of the ball and explain why it does not show wave nature.
Answer» SOLUTION :Here m =100 g =0.1 kg `h=6.626 xx10^(-34)` JS According to DE BROGLIE equationwavelength`lambda=(h)/(mv)` `=238.5 xx10^(-34) m^(-1)` so the wavelength is very small the wave naturecannot be detected
