It has been shown that the behavior of particles at tir and subatomic levels cannot be explained by bi, classical Instead, a new branch of physics, quantum physics h developed to explain the behavior of these particles. It reveals how everything in the universe is connected, and how the universe works. It is considered to be pn of the mo! complex and challenging fields of physics
Quantum physics was first developed by Danish physicist NielsBohr in 1913, who said that electrons circle around the nucleusof an atom. According to him, when light hits an electron it will absorb or emit only certain amounts of energy. This explains why some colors of light can be absorbed but not others. The word "quantum" means "amount" in Latin. Bohr's theory states that the amount of energy an electron has can only have certain values or "quantums". This is what differentiates it fromclassical physics, which says that there are no limits to how much energy an object may have.
It is very important to understand that quantum physics is still a relatively new field in science, and many of its theories are still being developed and tested.
