The decay constant ( $\lambda$ ) and the half-life ( $T$ ) of a radioactive isotope are related by t

Question

The decay constant ( $\lambda$ ) and the half-life ( $T$ ) of a radioactive isotope are related by the formula,

Professor PC Thomas Classes · Answer

Half-life $T$ is related to the decay constant by $T = \frac{\ln 2}{\lambda}$, so $\lambda = \frac{\ln 2}{T}$.
