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

Options

A. `lamda=(log_(10)2)/(T)`
B. `lamda=(log_(e)2)/(T)`
C. `lamda=(log_(2)10)/(T)`
D. `lamda=(log_(2)e)/(T)`

Answer

B

Explanation

The relation between decay constant `lamda` and half-life T can be given as
`T=(0.693)/(lamda)`
`:.T=(log_(e))/(lamda)`
