The relation between half`-`life period `(t_(1//2))` and disintegration constant `(lambda)` is expressed as a)`lambda=(0.693)/(t_(1//2))` b)`lambda=(0.693)/(t_(1//2))` c)`lambda=(693)/(t_(1//2))` d)`lambda=693t_(1//2)`

Options

A. `T_(1//2) = (ln2)/(lambda)`
B. `T_(1//2) ln2 = lambda`
C. `T_(1//2) = (1)/(lambda)`
D. `(lambda + T_(1//2)) = (ln)/(2)`

Answer

A
