Fundamental and Quantum Review #6

Postby keyaluo4C » Sun Nov 04, 2018 8:44 pm

Could someone explain the question #6 to me in UA Mr Ronald Yang's review problems and how he got to his solution again?

So we are solving for the final energy level. We know the initial value is in the ultraviolet region, therefore n=1 initially. the final value must be greater than n=1 and if we use En=-hR/n^2 Because we know the wavelength of the final observed hydrogen line we can find the change in energy and therefore we can find the final value of n.
