Half-Life Action (3)!!!
- Tim Brzezinski
Recall the half-life of a substance is defined to be the amount of time it takes for half of ANY AMOUNT of that substance to decay. This applet illustrates that the half-life of an substance is INDEPENDENT OF (i.e. DOES NOT DEPEND UPON) the INITIAL AMOUNT of SUBSTANCE. Thus, at any point in time, the half-life of a substance always remains invariant. To illustrate this, move the pink point anywhere you'd like and then slide the black slider.
