FAQs on Lecture 3: Postulates of Quantum Mechanics Video Lecture - Quantum Mechanics for GATE - GATE Physics

1. What are the key postulates of Quantum Mechanics?
Ans. The key postulates of Quantum Mechanics include the wave-function postulate, measurement postulate, superposition postulate, and uncertainty principle.
2. How do the postulates of Quantum Mechanics differ from classical physics?
Ans. The postulates of Quantum Mechanics differ from classical physics in that they involve probabilities and uncertainties, rather than definite values and deterministic outcomes.
3. Can you explain the measurement postulate in Quantum Mechanics?
Ans. The measurement postulate in Quantum Mechanics states that the act of measurement collapses the wave function of a system, resulting in the determination of a definite outcome.
4. How does the superposition postulate relate to the concept of quantum states?
Ans. The superposition postulate in Quantum Mechanics states that a quantum system can exist in multiple states simultaneously, with each state contributing to the overall wave function of the system.
5. What is the significance of the uncertainty principle in Quantum Mechanics?
Ans. The uncertainty principle in Quantum Mechanics, formulated by Heisenberg, states that it is impossible to simultaneously know both the precise position and momentum of a particle, highlighting the inherent uncertainty in quantum systems.
