A monochromatic laser is exciting hydrogen atoms from the n=2 state to the n=5 state.
Eventually, all of the excited hydrogen atoms will emitphotons until they fall back to the ground state. How manydifferent wavelengths can be observed in this process?
What is the shortest wavelength min observed?
