The wavelength of `K_(a)` , X-rays for lead isotopes `Pb^(208),Pb^(206),Pb^(204)" are"lambda_(1),lambda_(2)" and"lambda_(3),` resperctively. Then

A

`lambda_(1)=lambda_(2)gtlambda_(3)`

B

`lambda_(1)gtlambda_(2)gtlambda_(3)`

C

`lambda_(1)ltlambda_(2)ltlambda_(3)`

D

`lambda_(2)=sqrt(lambda_(1)lambda_(3))`

Text Solution

Verified by Experts

The correct Answer is:
D
Since, atomic numer are same `lambda_(1)=lambda_(2)=lambda_(3)`
` or " " lambda_(2)=sqrt(lambda_(1)lambda_(3))`
