Quantum mechanics is a physical theory used to explain the behavior and interactions of subatomic particles. This theory was developed to understand and describe phenomena in the microscopic world. Quantum mechanics is known for its successful explanation of phenomena in the microscopic world, and has a wide range of applications in modern physics.

Wave mechanics is a branch of quantum mechanics and is a mathematical framework used to describe the behavior of subatomic particles. Wave mechanics deals with the wave functions of particles, specifically through the Schrödinger Equation. This theory provides information about the specific position and momentum of particles, as well as their energy levels.
Wave mechanics is a very successful theory for understanding and explaining phenomena in the microscopic world. It mathematically models the behavior of subatomic particles and explains various experimental results.
Some basic properties of wave mechanics:
Wave Function (Ψ): It expresses the probability of finding a particle at a certain location or at a certain time.
Schrödinger Equation : Describes how the wave function evolves depending on time and space coordinates.
Possible Energy States: Describes the possible energy levels and possible locations of a particle.
Wave-Particle Duality: It states that particles have both particle and wave properties at the same time. It states that matter waves behave as waves and interact like particles.
Uncertainty Principle: It is not possible to determine exactly one property of a particle (for example, its position and momentum) simultaneously. This states that nature contains a fundamental uncertainty that cannot be precise in certain measurements.
The Bohr atomic model is a model of the atom proposed by Danish physicist Niels Bohr in 1913. This model attempts to overcome some of the limitations of the earlier Rutherford model.
The model was successful in accurately describing certain spectral lines for the hydrogen atom, but it was not fully applicable to heavier atoms. Quantum mechanics, developed in later years, provided a more precise explanation of atomic behavior and was considered an evolution of the Bohr model. Quantum mechanics stands out as a theory that mathematically describes the behavior of the subatomic world and quite successfully explains experimental results. Quantum mechanics includes the wave-particle duality of particles and the uncertainty principle. It is impossible to measure the exact position and momentum of electrons simultaneously with certainty; this is known as the uncertainty principle.
