Question:

WHAT DO YOU UNDERSTAND BY PHYSICAL SIGNIFICANCE OF THE ENERGY TIME UNCERTAINITY RELATION

Answer:

Uncertainty principle of energy and time $\Delta E\Delta t \geq \hbar$ means that the quantum system being in a state with uncertainty energy $\Delta E$ will be in this state for the time $\Delta t$ , or other meaning is that for measurement of energy with accuracy $\Delta E$ it takes the time $\Delta t$ for the measurement.
