18. (WCSP[x], 6 points) A student experimentally observed three (3) emission lines from a hydrogen tube in her spectroscope. One of these was 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.
