Question
A radioactive substance has a decay constant equal to $4.4 \times 10^{-8} \mathrm{s}^{-1} .$ What is the half-life of this substance?
Step 1
Step 1: The half-life of a radioactive substance is given by the formula: \[ T_{1/2} = \frac{\ln(2)}{\lambda} \] where \( \lambda \) is the decay constant and \( \ln(2) \) is the natural logarithm of 2. Show more…
