Problem

Which of the following gives the correct mathematical relationship between the half-life,

t_{\frac{1}{2}}

, and the decay constant,

\lambda

? a.

t_{\frac{1}{2}} = \frac{1}{\lambda}

t_{\frac{1}{2}} = \frac{\lambda}{\ln 2}

t_{\frac{1}{2}} = \frac{\ln 2}{\lambda}

t_{\frac{1}{2}} = \ln 2 \times \lambda
