Suppose that an electron trapped in a one-dimensional infinite well of width 322 pm is excited from its first excited state to the state with n = 5.
(a) What energy (in eV) must be transferred to the electron for this quantum jump? The electron then de-excites back to its ground state by emitting light, In the various possible ways it can do this, what are the
(b) shortest,
(c) second shortest,
(d) longest, and
(e) second longest wavelengths (in nm) that can be emitted?
An 8.00 point mass and a 15 point mass are held in place 50 apart. A particle of mass is released from a point between the two masses 13.00 from the 8 mass along the line connecting the two fixed masses.
