Question:

The relation between half-life of a radio nuclide denoted by \(T_{\frac{1}{2}}\)and average life of a radio nuclide denoted by τ, is

Options:

\(T_{\frac{1}{2}}=τIn2\)

\(τ=T_{\frac{1}{2}}In2\)

\(T_{\frac{1}{2}}=\frac{1}{τ}\)

\(T_{\frac{1}{2}}=τ\)

Correct Answer:

\(T_{\frac{1}{2}}=τIn2\)

Explanation:

$ T_\frac{1}{2} = \frac{ln2}{\lambda}$

$ \tau = \frac{1}{\lambda}$

$ T_\frac{1}{2} = \tau ln2 $
