Show that the energies for the odd solutions are the same as the even-numbered energies of an infinite well of length 2a. Hint: Use lazy physics here; there is no need to re-solve anything. Which option best describes the energy relationship?

A) They are equal.
B) They differ by a factor of 2.
C) No relationship between odd and even energies.
D) Odd energies are half of even energies.
