Calculate the ratio of half-life to the mean life of a radioactive sample . If `lambda` be the decay constant of a radioactive sample.

A

0.693

B

0.746

C

1/0.693

D

`(0.693)^(2)`

Text Solution

Verified by Experts

The correct Answer is:
A
Half - life = `0.693 / lambda`
Average life or mean life = `1 /lambda `
Ratio = `(0.693/lambda)/(1/lambda)` = 0.693
