T1 and T2 are the half-lives of two radioactive elements of decay constant A, and Az respectively then the value of T,/Tz is .......?
Correct answer: D. λ2/λ1
- A. λ2 = λ1
- B. λ1 . λ2
- C. λ1 / λ2
- D. λ2/λ1
Explanation
T = 0.693/λ. Hence T1=0.693/λ1 and T2=0.693/λ2 So the value of T1/T2 would be (0.693/λ1) / (0.693/λ2), which would equate to "λ2/λ1".
