Quantum mechanics is the branch of physics that studies the behavior of matter and energy in the presence of an observer. It is the foundation of modern physics and the theory of the wave-particle duality.

The characteristic equation is a mathematical equation that describes the behavior of a quantum system. It is used to determine the energy levels of a system, the allowed values of the angular momentum, and the properties of the wave function.

The characteristic equation is also known as the dispersion relation or the eigenvalue equation.

### Q: What is meant by characteristic equation?

A: The characteristic equation is a polynomial equation whose roots are the eigenvalues of a square matrix.

### Q: How do you find characteristic equation?

A: The characteristic equation is the equation that is satisfied by the characteristic roots of the matrix.

### Q: What is the quantum mechanics equation?

A: There is no one “quantum mechanics equation.” There are many different equations that are used in quantum mechanics, depending on the specific situation.

### Q: What is characteristic equation of eigenvalues?

A: The characteristic equation of an eigenvalue is the equation that must be solved in order to determine the eigenvalue.
