Hi guys, can anyone help me with this question?
The electron in a hydrogen atom is excited to the n=5 shell and emits electromagnetic radiation when returning to lower energy levels. Determine the number of spectral lines that could appear when this electron returns to the lower energy levels, as well as the wavelength range in nanometers.

Hi! So to find the amount of spectral lines I would consider where the electron begins, n=5, and what the lowest shell it can go to which would be n=1 and just subtract the second number from the first. To get the wavelength range, you would have to solve for the wavelength of the transition of n=5 to n=4 and n=5 to n=1 to get the full range. To do this you can use the equation v=R((1/n^2)-(1/n^2)) to get the frequencies of each of the transitions and then use c=frequencyxwavelength to get the respective wavelengths which you could then convert into nanometers. I hope this helps!
