Answer 1

Answer:

here is your ans

Explanation:

Half life of a radioactive substance(\tau_{1/2}τ  

1/2

​  

) measures the time it takes for a given amount of the substance to become reduced by half as a consequence of decay, and therefore, the emission of radiation.

It is related to radioactive decay constant kk as \tau_{1/2}=\dfrac{ln2}{k}τ  

1/2

​  

=  

k

ln2

​  

.

Also its relation with mean life \lambda_m=\dfrac{1}{k}λ  

m

​  

=  

k

1

​  

 is

\tau_{1/2}=\lambda_m ln2τ  

1/2

​  

=λ
