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 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 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?
Answer» ng to de-Broglie's formula,where, h is planck's constant. Putting in the values,λ = 2.39 x 10⁻³⁴The WAVELENGTH is of the order 10⁻³⁴, which is very SMALL. HENCE for MACROSCOPIC objects, wavelength is negligibly small and hence not visible.
