In Geiger-Mersden experiment, detection of `alpha`-particles scattered at a particular angle is done by

A

counting flashes produced by `alpha`-particles on a ZnS coated screen

B

counting spots produced on a photographic film

C

using a galvanometer detector

D

using a Geigher-conuter

Text Solution

Verified by Experts

The correct Answer is:
D

Many of the `alpha`-particles pass through the foil. It means that they do not suffer any collisions., only about 0.14% of the incident `alpha`-particles scatter by more than `1^(@)` and about 1 in 8000 deflect by more than `90^(@)`.
