Background: A monochromatic laser is exciting hydrogen atoms from the n=2 to state to the n=5 state.
Question: What is the shortest wavelength observed?
-I believe that it will be from n=5 to n=4, but I am not sure what equation to use or how to use the n values...
Answer: ?? nm
short wavelenght, highest energy. Highest energy means greatest possible change.
So calculate yours, then try 2 to 5
