1a. Given y, and y, are stationary states of the same Hamiltonian with energies E, and E2 respectively. What is the condition on E, and E, such that the wavefunction ya +y, is also a stationary state? 1b. Same as in the above problem, suppose at 1 = 0 the particle has wavefunction ya +42. Write down (without doing any mathematics) its wavefunction at time t. You can assume that it is not in a stationary state so that your condition in the above question does not hold. 10. Sketch in the following diagram the probability density of a particle in an infinite square well potential when its quantum number is very largeſ, i.e., like a classical particle. ly 0 a 1d. Suppose y, is the lowest energy state of a quantum harmonic oscillator whose energy is E.. Explain in words (no mathematics) why a_y, must be a trivial solution, i.e., a_y. =0.
