Question

The statements in the following list all refer to Quantum Physics. Check the boxes of the THREE CORRECT statements.

1. The more massive a particle is, the bigger its de Broglie wavelength.

2. There is a fundamental limit to the precision with which the position and the energy of a particle can be simultaneously known.

3. Classical and quantum mechanics are in complete contradiction.

4. There is a non-zero probability of finding a particle outside a finite square well, even if its total energy is smaller than the potential energy.

5. The quantum numbers s and m_s determine the magnitude of spin angular momentum and its z-component relative to an arbitrarily defined z-axis.

6. The configuration 1s³ is not physically possible.

Answer 1

1. first one is incorrect because de Broglie wavelength is inversely proportional to mass.

2.Incorrect, Uncertainity principle relate position and momentum , and energy and time.

3.Correct. classical is determinastic and quantum is probabilistic.

4.Correct. This phenomena called Quantum tunneling.

5.Correct.

6.Incorrect. Because electron have only two orientation up and down.
