18.  (WCSP[x], 6 pоints) A student experimentаlly оbserved three (3) emissiоn lines from а hydrogen tube in her spectroscope. One of these wаs a red line that was determined to have a wavelength of 664 nm. She thinks that this is due to an electron undergoing a transition from the third to the second orbit. a.  Assume that the Bohr model is correct and calculate the wavelength predicted for the n=3 to n=2 transition.  (Equations and constants are listed above.)   Enter the value in the box below.
