The momentum of a moving particle 'A' is twice that of another particle 'B' if the wavelength associated with the motion of A be `5xx10^(-8)m`, find the wavelength associated with the motion of B.

Explanation

`lamda_(A)=(h)/(mv),lamda_(B)=(h)/((1)/(2)mv)" "therefore (lamda_(A))/(lamda_(B))=(h//mv)/(h//(1)/(2)mv)=(1)/(2)`
`therefore lamda_(B)=2lamda_(A)=2xx(5xx10^(-8))=10^(-7)m`
