Does the linear momentum operator depend on the problem to be solved in quantum mechanics? If yes, explain why, if no, then what is it? What is the eigenvalue spectrum for this operator?4. A linear oscillator of frequency stays in an environment of absolute temperature T. What is the probability that the oscillator is in its first excited state (with energy)?
- 811. As limited by the Heisenberg's uncertainty principle the precision in the determination of particle's position would provide the same precision in the determination of particle's momentum. the least time measurement of energy transition would give exact energy for thal transition. the more precisely a particle's position cal be specified, the broader measurement of values could be obtained for momentum. two simultaneous measurements will always provide undefined values.124. For a 1-kg ball in a l-m² square two-dimensional box (i.e., L = 1 m), what is the lowest quantum energy allowed? If the ball had this kinetic energy, how long would it take to travel from one side of the box to the other? Is this time something that you think you could measure?
