Can anyone explain the experiment? i am having a big doubt in it.

Bob S said:First of all, if you write out the equations for Rutherford scattering of alpha particles from a point nuclear charge, you get an equation that has an angular dependence something like sin4(θ/2) (my memory fails a little). If it deviates from this at large angles, then the alpha particle is hitting something. I did this experiment in a physics lab many years ago, and my biggest problem was that the gold foil stuck to my fingers.
johncena said:A thin gold foil contains infinite number of atoms.So, by passing alpha rays to this foil , how was Rutherford able to explain the structure of a single atom?

Rutherford's gold foil experiment was a series of experiments conducted by Ernest Rutherford in 1910 to study the structure of the atom. It involved firing alpha particles at a thin sheet of gold foil and observing how they interacted with the atoms in the foil.
Rutherford's gold foil experiment was important because it provided evidence for the existence of a small, dense, positively charged nucleus at the center of an atom. This disproved the previously accepted "plum pudding" model of the atom and paved the way for our current understanding of atomic structure.
Rutherford's gold foil experiment involved firing alpha particles (positively charged particles) at a thin sheet of gold foil. Most of the alpha particles went straight through the foil, but a small percentage were deflected at large angles or even bounced back. This showed that the positive charge of the atom was concentrated in a small, dense nucleus at the center.
The results of Rutherford's gold foil experiment showed that most of the alpha particles passed through the gold foil with minimal deflection, indicating that most of an atom is made up of empty space. However, a small percentage of alpha particles were deflected at large angles or even bounced back, which led to the discovery of the atomic nucleus.
Rutherford's gold foil experiment had a major impact on our understanding of the atom. It provided evidence for the existence of a small, dense, positively charged nucleus at the center of an atom and disproved the previously accepted "plum pudding" model. This experiment also paved the way for further research and advancements in the field of atomic structure.
