What Is The Relationship Between Half-life And Decay Constant?

What Is The Relationship Between Half-life And Decay Constant? The time required for half of the original population of radioactive atoms to decay is called the half-life. The relationship between the half-life, T1 / 2, and the decay constant is given by T1 / 2 = 0.693/λ. What is the relation between mean life and
