Hermitian operator is a mathematical concept in linear algebra and quantum mechanics where the operator is equal to its own conjugate transpose.

• Hermitian operator is a linear operator that is equal to its own conjugate transpose.

• In quantum mechanics, observables are represented by Hermitian operators.

• Hermitian operators have real eigenvalues and orthogonal eigenvectors.

• Example: The position operator in quantum mechanic

Forced vibration is when a system is subjected to an external force causing it to oscillate at a frequency different from its natural frequency.

• A common example of forced vibration is a child on a swing being pushed by a parent at a frequency different from the swing's natural frequency.

• Another example is a tuning fork being struck with a hammer, causing it to vibrate at a frequency determined by the force of the strik...read more
