Quantum Mechanics II - SS3 Physics Past Questions and Answers - page 1

The Schrödinger equation is a fundamental equation in quantum mechanics that describes the time evolution of a quantum mechanical state. The equation is a partial differential equation that describes how the wave function of a physical system changes over time. The wave function is a mathematical function that describes the probability amplitude of the system being in a particular state at a particular time.

The Schrödinger equation is the fundamental equation of quantum mechanics, and it is used to describe a wide variety of physical systems, including atoms, molecules, and solid-state materials.

In quantum mechanics, a quantum state is a mathematical description of a physical system. Quantum states are represented by wavefunctions, which are complex-valued functions that describe the probability amplitude of a quantum system being in a particular state.
