1. Please answer question throughly and detailed.
Consider a particle of mass m in a 1-dimensional infinite square well potential
0,
(-a < x <a)
V (x) =
00, elsewhere
At time t=0, the particle is in a state described by the wave function
А(а + х), —а <r<0
А(а — х), 0 <I<a
0,
V (x,0) =
elsewhere
where A = constant.
(a) Find the probability that the particle will be found in the ground state at a later time.
(b) Calculate the probability that an energy measurement will yield the energy of the first excited state.
