2. An entity is in a 2-D infinite well of dimension 0≤x≤ a 0 ≤ y ≤ b The wave function of this entity is given by y(x, y) = C sin(kxx) sin(kyy) (a) Determine the values of kx, ky, and C. (b) If a = b, determine the total energy of the system. Draw the energy diagram up to the 5th excited level and explain the degeneracies (if present). (10 marks) (10 marks)
