Why we do not see the wave properties of a baseball ?

Explanation

According to de Broglie equation `lambda = ( h )/( mv) `i.e., ` lambda prop ( 1)/( m ) `. The de broglie wavelength varies inversely with the mass and velocities of a base ball. On comparing the mass of a base ball with electron, base ballhas most significant mass than an electron. Hence resulted wavelength will be small and is difficult to observe.
