Two particles A and B are in motion. If the wavelength associated with the particle A is 5.0xx10^(-8)m ,the wavelength of particle B having momenthalf of A is

Answer»

<P>`2.5xx10^(-8)m`
`1.25xx10^(-8)m`
`1.0xx10^(-7)m`
`1.2xx10^(-8)m`

SOLUTION :`lamda_(A)=h/(p_(a))""lamda_(B)=h/(p_(B))`
`p_(B)=p_(A)//2`
`(lamda_(B))/(lamda_(A))=(P_(A))/(P_(B))=(P_(A))/(P_(A//2))=2`
`:.lamda_(B)=2xxlamda_(a)=2xx5xx10^(-8)m=1xx10^(-7)m`
