Wavelength HELP!!!! 1. The problem statement, all variables and given/known data Calculate the wavenumber (v=1/lambda) and the wavelength of the first transition in the visible region of the atomic spectrum of hydrogen. I KNOW THE ANSWER..... 656.3 nm. I just don't have a clue how they got that answer, I do know that I had to use Rydberg's Constant (1.097X10^7 m ^-1) but I have no idea what to do or how to do it. Thank you anyone who wants to take time and help me. And I don't know if this will mean anything but it is Inorganic Chem 430. 2. Relevant equations 1/λ=R(1/n12-1/n22) 3. The attempt at a solution I have been at this for hours trying to find out how to calculate everything. and IDK if it's my ti-84 plus edition that is doing the math wrong or what but I cannot find out how to compute this.... 1. The problem statement, all variables and given/known data No variables were given to me except rydberg's constant.
