The graph below represents the ground state wave function of an electron in a finite square well potential of width L. The potential is zero

The graph below represents the ground state wave function of an electron in a finite square well potential of width L. The potential is zero at x = 0.(I got lamda = 1950 picometer

The ground state wavefunction

a. What is the approximate kinetic energy of the electron inside the well?

b. If the electron were in the ground state of an infinite square well of the same width L , what would be its kinetic energy?

amplitude 0.05 -0.05 - 1200 -800 ground state wave function -400 0 position (picometers) 400 800 1200
