☢️ Half-Life Calculator
Calculate half-life, remaining quantity, initial quantity, or time elapsed using the exponential decay formula N = N₀ × (1/2)^(t/t½).
The Half-Life Formula
Half-life describes the time required for a quantity to reduce to half its initial value. The formula N = N₀ × (1/2)^(t/t½) relates the remaining quantity N, initial quantity N₀, elapsed time t, and the half-life t½.
Applications of Half-Life
Half-life is widely used in nuclear physics (radioactive decay), pharmacology (drug metabolism), chemistry (reaction rates), and archaeology (carbon dating). The concept applies to any process that follows exponential decay.
