A particle of mass m in an infinite well has its initial wavefunction ψ (x,0) = A[ψ1(x) +ψ3(x)] where ψ1(x) and ψ3(x) are stationary states. The boundaries of the well are x = 0 and x = a.
a) Find the value of A(Normalisation). (The stationary statesare orthogonal,)b) What's Ψ (x,t).c) I f I know the energy of the particle, what values could Iget and with what probabilities?d) What is the expectation value of energy?
