### Spectral Lines

Just checking, when a Sapling problem asks how many spectral lines there are when an electron returns to a lower level from n=7 for example, is the answer 6 because a line appears between the drop from 7 to 6, 6 to 5, 5 to 4, etc. all the way to 1?

Exactly, this is the same method I used on sapling and got the correct answer. I do believe this is how to solve this type of question. It would be the only way that really made sense, you should see one line for each energy level transition.

Hi! yep you are correct, the lines refer to the distinct changes of energy possible so you thought process of 7-6,7-5,7-4,7-3,7-2,7-1 is right!
