The wavelength of `K_(a)` , X-rays for lead isotopes `Pb^(208),Pb^(206 – InterviewSolution

InterviewSolution

1.	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. ThenA. `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))`
Answer» Correct Answer - D Since, atomic numer are same `lambda_(1)=lambda_(2)=lambda_(3)` ` or " " lambda_(2)=sqrt(lambda_(1)lambda_(3))`
