Rydberg's Equation

Postby Kim Vu 2G » Thu Oct 08, 2015 9:54 pm

The problem says, calculate the wavelength of light emitted when an electron in a hydrogen atom makes the transition from n=5 to n=3. How would you solve this equation? Using En= -hR/n^2 or v=R(1/n1 ^1) - (1/n2^2)?

Either way is acceptable, although you will not be given the Rydberg equation on quiz and test formula cover sheets, so use it at your own risk. Calculate the final and initial energy levels, calculating the change in energy and from that change calculating the wavelength is a more robust way to approach the problem.
