Relaxation Time

Relaxation time refers to the period it takes for a system—such as a material or a physical process—to return to its normal or equilibrium state after being disturbed. For example, if a heated metal cools down after heating is stopped, the relaxation time is how long it takes for the temperature to stabilize. It is a measure of how quickly a system responds to changes and settle back to balance. In physics and engineering, understanding relaxation time helps in analyzing how systems behave over time after disturbances.
