In Rutherford's experiment, alpha-particles got deflected through various angles in different proportions. How is this observation made?

Expert Answer:

In order to detect alpha-particles after scattering, zinc sulphide screen was used. When alpha-particles strike the zinc sulphide screen, they produced flashes of light which were detected. By examining these flashes on different portions of screen, it was possible to determine proportions of alpha-particles which got deflected through various angles.
