Calculate the de Broglie wavelength of a ball of mass `0.1 kg` moving with a speed of `30 ms^(-1)`

Text Solution

Verified by Experts

`lambda = (h)/(mv)=(6.6xx10^(-34))/(0.1xx30)=2.2xx10^(-34)m`
This is apparent that this wavelength is too small for ordinary observation.
Although the de Broglie equation is applicable to all material objects but it has significance only in case of microscopic particles.
