The relationship between decay constant `lamda` and half-life T of a radioactive substance is

The relationship between distintegration constant (lambda) and half-life (T) will be

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

Assertion Two different radioactive substances have initially same number of nuclei. Their decay constants are lamda_(1)and lamda_(2)(ltlamda_(1)). Then, initially first radioactiv substance decays at faster rate. Reason Half-life of first radioactive substance is less.
