According to de Broglie, matter should exhibit dual behaviour, that is both particle and wave like properties. However, a cricket ball of mass 100g does not move like a wave when it is thrown by a bowler at a speed of 100km/h. Calculate the wavelength 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 100g does not move like a wave when it is thrown by a bowler at a speed of 100km/h. Calculate the wavelength of the ball and explain why it does not show wave nature.
Answer» SOLUTION :`m = 100g = 0.1 kg, V = 100 km//hr = (100 XX 1000m)/(60 xx 60s) = (1000)/(36) ms^(-1)` `LAMDA = (h)/(mv) = (6.626 xx 10^(-34) kg m^(2) s^(-1))/((0.1 kg) (1000//36 ms^(-1))) = 238.5 xx 10^(-36) m` As the wavelength is very small, the WAVE nature cannot be detected
