Find de Broglie wavelength associated with a tennis ball of mass 60g moving with a velocity of 10 `m*s^(-1)`.

Text Solution

Verified by Experts

de Broglie wavelength, `lamda=(h)/(mv)`
Here, `h=6.626xx10^(-34)J*s`
`m=60g=60xx10^(-3)kg=6xx10^(-2)kg,v=10m*s^(-1)`
`therefore lamda=(6.626xx10^(-34))/(6xx10^(-2)xx10)=1.105xx10^(-33)m`
