$The relation between half life (T) and decay constant (λ) is$

Topic: JEE PYQ

Answer: A. Full step-by-step solution below.

A $λT = log_{e} 2$
B $λT = 1$
C $λ = log 2 T$
D $λT = 1 2$

Correct answer: A

Solution

(a) The relation between half life (T) and decay constant (λ) is T = \frac{ln 2}{λ} = \frac{log _{e} 2}{λ} or Tλ = log_{e} 2
