Stationary State
Definition
The term stationary state refers to a concept in physics, particularly quantum mechanics, where a system remains unchanged over time. In simple terms, it describes a state where the properties of a system do not evolve with time.
Origin
The idea of a stationary state originated from the work of physicists such as Niels Bohr and Max Planck in the early 20th century. They proposed that electrons in an atom occupy specific energy levels, and each level is associated with a distinct stationary state.
Characteristics
In a stationary state, the system's energy, momentum, and other relevant quantities remain constant. Any transition between different stationary states requires the absorption or emission of a specific amount of energy, corresponding to the difference in energy levels.
Quantum Mechanics
In quantum mechanics, stationary states are represented by wave functions that satisfy the time-independent Schrödinger equation. These wave functions describe the probability amplitudes of finding a particle in a particular state at a given time.
Applications
Stationary states play a crucial role in understanding the behavior of atoms, molecules, and other quantum systems. They are utilized in various areas of physics, including spectroscopy, quantum chemistry, and solid-state physics.
Conclusion
Overall, stationary states are fundamental concepts in quantum mechanics that help explain the stable behavior of physical systems at the microscopic level. By studying and analyzing these states, scientists can gain insights into the underlying principles governing the behavior of matter and energy.
