What will be the wavelength of a ball of mass 0.1 kg moving with a velocity of 10 `ms^(-1)`

Text Solution

Verified by Experts

According to the de Broglie equation
`lambda =(h)/( mv) `
`lambda =(6.626 xx 10^(34) js)/( (0.1 kg 10 ms^(-1))`
where m= 0.1 kg
v=10 `ms^(-1)`
`h= 6.626xx 10^(34) Js`
`=6.626 xx 10^(34) kg ^(-1) m^(-1) s^(2) ` but `J= kg m^(2) s^(2)`
`=6.626 xx 10^(34) m`
