Applet: Decay

Here we study radioactive decay. Shown (red dots) is a large number of identical atomic nuclei, each obeying the same decay law. Now select the half life time of the nuclei with the slider, press the START button, and watch them decay away as a function of time (displayed in the upper right corner). Shown also is a histogram (in green) of the number of nuclei remaining at a given time.
