Quantum mechanics is a branch of physics that studies the behavior and interactions of subatomic particles, such as atoms and electrons.
Quantum mechanics was developed by several scientists, including Max Planck, Niels Bohr, Werner Heisenberg, and Erwin Schrödinger, in the early 20th century.
The Schrödinger equation is a fundamental equation in quantum mechanics that describes the time evolution of a quantum system. It is used to calculate the probability of finding a particle in a certain location at a certain time.
Energy levels in quantum mechanics refer to the discrete values of energy that an electron can have in an atom. These energy levels are quantized, meaning they can only have certain values and not any value in between.
Quantum mechanics differs from classical mechanics in that it describes the behavior of particles at the subatomic level, whereas classical mechanics deals with the behavior of larger objects. Quantum mechanics also introduces the concept of uncertainty, where the exact position and momentum of a particle cannot be simultaneously known.
