This simulation demonstrates how alpha particles scatter when fired at a gold foil, showing why most pass straight through while a rare few rebound sharply off a concentrated nucleus.
Fire alpha particles at the foil and adjust settings like nucleus size or particle speed to see how the scattering pattern changes, then compare the results to what the plum pudding model would have predicted.
Use the controls to launch alpha particles, adjust the nucleus and foil properties, and observe the resulting scattering angles in real time.
Geiger and Marsden had to sit in a darkened room and count individual flashes of light on the detection screen by eye for months, since automated particle detectors did not yet exist.
