We assume that a particle is confined in an innite potential well and is described by a superposition of eigen states 'P = (21411 + 3% + \"13). a) Calculate the energy expectation value . (5 points) b) If an energy measurement is conducted, what is the probability of finding E2? (5 points) \fSo, please, when ever a eigenstate of parbile (or a normal state) is given then first check if it normalized or not ? [ Because , After all in the quantum mechanics all calculations are probabilistic, not exact . answer. 75 This is the main difference between classical mechanics and quantum physics.
