1. Complete the algebra that leads to the transcendental equations given by (155.5), (155.6) and (155.7) of the finite 1-d square well.
2. For advanced students, find the condition on (or value of) well depth, V0, and well width, a, such that only two 1-d bound states exist and that the photon emitted has a wavelength of 5000A (one must be symmetric and the other antisymmetric in order to emit light, why?).
