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.

Explanation

Here m =100 g =0.1 kg
`h=6.626 xx10^(-34)` js
According to de broglie equation wavelength `lambda=(h)/(mv)`
`=238.5 xx10^(-34) m^(-1)`
so the wavelength is very small the wave nature cannot be detected
