Q. The relationship between $\lambda$ and half life $(T_{1/2})$ of a radioactive substance is
A) $\lambda = \frac{\log_{10}2}{T_{1/2}}$
B) $\lambda = \frac{\log_{e}2}{T_{1/2}}$
C) $\lambda = \frac{\log_{2}10}{T_{1/2}}$
D) $\lambda = \frac{\log_{2}e}{T_{1/2}}$
Explanation
The correct answer is Option B: $\lambda = \frac{\log_{e}2}{T_{1/2}}$.
