An electron is trapped in one-dimensional region of length 1.00 x 10-10 m Calculate the
(a) energies of the ground state and the first two excited state
(b) energy that must be supplied to excite the electron from the ground
state to the second excited state
(c)..From the second excited state, the electron drops down to the first
excited state.Calculate the energy released in this process
