The half-life formula is commonly used in nuclear physics where it describes the speed at which an atom undergoes radioactive decay. The formula for the half-life is obtained by dividing 0.693 by the constant λ.
This calculator computes any of the values in the half-life formula given the rest values. It also converts between half-life, mean lifetime, decay constant.
The half-life calculator is a tool that helps you understand the principles of radioactive decay. You can use it to not only learn how to calculate half-life, but also as a way of finding the initial and final quantity of a substance or its decay constant.
27 sie 2024 · To find the half life of a substance, or the time it takes for a substance to decrease by half, you’ll be using a variation of the exponential decay formula. Plug in ½ for a, use the time for x, and multiply the left side by the initial quantity of the substance.
Free online half-life calculator. Calculate the time passed, original amount, half-life, or resulting amount based on any of the three values. Convert half-life to mean lifetime or decay constant.
Half Life Formula. The primary half life formula is: Nt is the quantity of substance remaining after time t. N0 is the initial quantity of the substance. t is the elapsed time. t1/2 is the half-life of substance. This half life equation allows scientists to anticipate how much of a material will remain at any given time.
This calculator will calculate the half-life, initial quantity, quantity remained, and time, with steps shown. There are units of mass of a substance with a half-life of units of time. In units of time, there will remain units of mass of the substance. Enter any three values.
