Problem 1: Fibre optics (2 points) Figure 1: Sketches of the geometry of an optical fibre A long cylinder of dielectric material can guide light via total internal reflection. This idea dates back to the 1870s and forms the basis of the modern fibre optics communication technology. As long as the diameter of these fibres is large compared to the wavelength of the infalling light, its wave nature is negligible and we can use Geometric Optics to study the propagation...

1. A quantum system goes into a time-dependent superposition of three real eigen- functions (energies E, E 2, E, all equally likely). Write down the total wave- function, and calculate the probability density. Express your answer in terms of the (co)sinusoidal interference terms. 2. Write down the time-dependent wavefunction for the particle a box that is in a superposition of the n = 2 and n = 4 states. Assume there is a 30%...
