A ball of mass 100 g is moving with a velocity of 100 `msec^(-1)`. Find its wavelength.

Text Solution

Verified by Experts

According to de Broglie equation,
`lambda =(h)/(mv)`
`m=100g =0.1 kg , v= 100 ms^(-1), h= 6.626 xx 10^(-34) kg m^(2)s^(-1)`
`lambda =((6.626 xx 10^(-34) kg m^(2)s^(-1)))/((0.1 kg )xx(100 ms^(-1)))=6.626 xx 10^(-35)m`.
