Question

explain the meaning of expectation value of a dynamical variable

Answer 1

Answer:

In quantum mechanics, the expectation value is the probabilistic expected value of the result (measurement) of an experiment. ... It is a fundamental concept in all areas of quantum physics.

Answer 2

Answer:

Expectation value of a dynamical variable is probabilistic expected value.

Explanation:

It is the term used in quantum mechanics.

As understood by the name, expectation value is probabilistic value.

It is the term used when we record observations in any experiment.

We can say that it is fundamental concept in quantum physics.

Concluding, we can say that it is the expectation value is the probabilistic expected value of the result or measurement of an experiment and is the one of the concept in areas of quantum physics.
