The half-life `(T)` and the disintegration constant `(lamda)` of a radioactive substance are related as

The average life T and the decay constant lamda of a radioactive nucleus are related as

Using the equation N = N_(0)e^(-lambdat) , obtain the relation between half-life (T) and decay constant (lambda) of a radioactive substance.
