Which of the following best describes the role of quantum numbers in quantum mechanics?
Which of the following best describes the role of quantum numbers in quantum mechanics?
- Quantum numbers are arbitrary values used to label different quantum states.
- Quantum numbers are continuous values that characterize the system such as mass, charge, or momentum.
- Quantum numbers correspond to eigenvalues of operators that commute with the Hamiltonian and fully characterize a basis state of a quantum system. (correct)
- Quantum numbers are related to classical mechanics and do not have a direct application in quantum systems.
What distinguishes quantum mechanics from classical mechanics in terms of observable quantities?
What distinguishes quantum mechanics from classical mechanics in terms of observable quantities?
- Quantum mechanics does not involve the concept of energy levels, unlike classical mechanics.
- Quantum mechanics leads to quantization of observable quantities, while classical mechanics allows for continuous ranges of values. (correct)
- Quantum mechanics deals with macroscopic systems, whereas classical mechanics deals with microscopic systems.
- Classical mechanics allows for discrete sets of integers or half-integers, unlike quantum mechanics.
