Calculate the wavelength of a body of mass 1 mg moving with a velocity of 10 m `sec^(-1)`.

Explanation

We know, `lamda=h/(mv)` Substitute the values m = 1 mg `= 10^(-6)` kg
`v=10msec^(-1)`
`H=6xx10^(-34)kgm^(2)s^(-1)`
`lamda=(6.626xx10^(-34)kgm^(2)s^(-1))/(10^(-6)kgxx10ms^(-1))`
`lamda=6.626xx10^(-29)m`
