$\lambda $ અને $({T_{1/2}})$ વચ્ચેનો સંબંધ શું છે?
(${T_{1/2}}=$ અર્ધઆયુ સમય $\lambda =$ ક્ષય નિયતાંક)
A
$\left(\lambda+ T _{1 / 2}\right)=\frac{ln }{2}$
B
$T _{1 / 2}=\frac{ln2}{\lambda}$
C
$T _{1 / 2}\; ln 2=\lambda$
D
$T _{1 / 2}=\frac{1}{\lambda}$
(AIPMT-2000)
Solution
(b) Relation between half-life ( $T_{1 / 2}$ ) of a radioactive substancce and its decay constant $\lambda$ is $\lambda=\frac{\log _{e} 2}{T_{1 / 2}}$
