Scattering Experiment

 

Scattering Experiment

Geiger and Marsden counted the deflections of alpha particles off gold foil at different angles. Use the simulation below to see their results!

The diagrams show the overhead and side views of their apparatus. Use the blue rotate buttons to rotate the microscope to different angles, and the graph will count how many particles are seen at this angle. The scale on the graph can be changed using the slide bar.

Spend more time looking at each angle to improve the accuracy on the graph. Geiger and Marsden spent weeks counting many thousands of particles.
