Let us model a pi-electron in a tyrosine, by assuming it is a particle trapped in a 2-dimensional square box. As you should know, the maximum of absorption is at about 280nM. Calculate the approximate size of the box used to model the tyrosine ring. Is this a reasonable model for the system?

(Hint: Provide an expression for the quantized energy levels of the electron and calculate the lowest energy corresponding to transition from the ground state to the excited state).
