What was the significance of the particles that reflected back from the gold foil?

Hope you mean the famous alpha particle scattering experiment performed. Alpha particle being positively charged get reflected. This confirms that there have to be positively charged particles within the gold foil. Moreover this scattering is very less compared to those just passing through gold foil. Rutherford as he made an observation of these he came to the conclusion that the positively charged core is so tiny and its radius of the order of 10-14 m. The radius of the atom was already found to be 10-11 m. So it becomes clear that the nucleus is 1000 times smaller than the atomic size

What happened to the alpha particles as they hit the gold foil?
They stop.
What causes some of the alpha particles to bounce straight back from the gold foil?
Alpha particles are composed of two neutrons and two protons, so they have a positive charge. When the alpha particles bounced straight back from the gold foil, this indicated that they had hit a particle of like charge, in other words a positively charged particle in the gold foil, which repelled the alpha particle.
In Rutherfords gold foil experiment shown in Figure 4-1 alpha particles that bounce straight back from the foil have struck in the gold atoms?
No, they struck the nucleus of the atom. Since the alpha particles are positively charged and nucleus is positively charged as well, they repelled each other and alpha particles are repelled back
The kind of particle Rutherford used to shoot through gold foil?
Rutherford shot high-energy alpha particles (two protons and two neutrons, or a helium nucleus) at the gold foil. A small fraction of these alpha particles bounced back, and that is how Rutherford discovered the nucleus.
Who discovered the nucleus using his gold foil experiment?
Rutherford by bombarding gold foil with positively charged particles and noting that some particles were widely deflected.
How did gold foil experiment show that there is a nucleus in the atom?
The gold foil experiment showed that there is a nucleus by how the alpha particles(positively charged particles) were deflected and changed course by the foil. It showed that the atom is made of mostly empty space because most particles went through the foil. Some of the particles though were deflected to the sides of the container around the foil and some where even reflected back at the light almost. Rethurford (or however you spell is name lol search it) theorized that there is a small nucleus that is positively charged that some particles came close to and were deflected away because the nucleus had an effect on them. Some particles hit the nucleus exactly and were reflected back only because it was positively charged if it had been negativly charged it wouldn't have went back to the light.

They stop.
When Rutherford performed his metal foil experiment did the alpha particles pass straight through the foil or bounce back?
The alpha particles beam is scattered.
When positively charged particles bounced back from the foil Rutherford called this?

How did the result of gold foil experiment lead Rutherford to recognize the existence of atomic nuclei?
By beaming alpha particles through gold foil and witnessing some of them deflecting, there had to be a mass larger than an alpha particle in the atomic structure. This disproved the plum pudding theory of the atom, as electrons would not have had enough mass to deflect the larger alpha particles.

Can tin foil be used on nuwave ovens?
Metal foil can be used (it will cause no harm) but I do not suggest it. Foil is reflective, and since the nuwave oven heats with infrared light, most would-be heat will probably we reflected away. If you put something dark on the foil so the light will not be reflected, that should work fine.
