If you use pencil, do not erase anything. If there are erasures, you get zero points. The wave function for a particle in an infinite square well (0<x<a) at t=0 is given by: 2 3π x Ψ ( x, 0 ) = sin( ). Which one of the following is the wave function at time t? a a 2 3π x sin( ) cos( E3t / ) (a) Ψ ( x, t ) = a a 2 3π x sin( ) exp(−iE3t / ) (b) Ψ ( x, t ) = a a (c) Both (a) and (b) above are correct. (d) None of the above. ...
