The half life of a radioactive element A...

The half life of a radioactive element A is same as mean life time of another radioactive element B.Initially, both have same number of atoms. B decays faster than A . Why?

Text Solution

Verified by Experts

`T_A=tau_B=1.44 T_B :. T_AgtT_B`
`lambda_A lt lambda_B`. Therefore, B decays faster than A.
