WHAT IS A REFLECTION?
"The throwing back by a body or surface light..." -Google
Let's say that light hit an object. Some of the light will hit the object and reflect back so that you can see it. The sun also reflects the things that you see outdoors.
Answer:
Ernest Rutherford observed that particles with a positive charge deflected when passing through a thin sheet of gold foil, concluding that the atom's positive part is small and dense.
Explanation:
The Ernest Rutherford experiment describes planetary model of an atom. According to the model, an atom has a tiny, compact, positively charged centre called a nucleus, where almost all of the mass is concentrated, while light, negatively charged particles called electrons orbit far around it, much like planets orbit the Sun. In his experiment, the observation that a positive charge is deflected through a thin sheet of gold foil led to the conclusion that the deflection some of the positive charge occurs in a small region of the atom. At the same time, the majority passed through the atom (which was also concluded to be empty space).
