Quantum Mechanics

   Quantum Mechanics Quantum mechanics is a branch of physics that deals with the behavior of matter and energy at the quantum level, which is the smallest scale of energy and matter. Quantum physics has led to many  discoveries, such as the wave-particle duality of light, the wave-particle duality of light, Heisenberg uncertainty principle. Classical mechanics is branch of physics that deals with the motion of macroscopic objects. Classical mechanics is based on three laws of motion formulated by Sir Isaac Newton. The principle  of classical mechanics are used to study the motion of planets and stars. Classical mechanics was extremely successful theory for describing the motion of macroscopic objects such as planets, stars and machines. However, it failed to explain certain phenomena, such as the behavior of light, the behavior of the atoms and  subatomic particles. Photo Electric Effects It is a phenomenon  where electrons are emitted from...
