So here they want us to consider the transitions, i assume for hydrogen, between n equals 1 and n equals 4.
00:14
So the energy levels will get closer to each other.
00:24
And the first question says how many emission lines are possible, considering only the four quantum levels.
00:33
Well, emission is going to be the release of energy.
00:37
So an electron could transition from 2 to 1, from 3 to 1, from 4 to 1, from 3 to 2, from 4 to 2, from 4 to 2, or from 4 to 3.
01:01
So that's a total of 1, 2, 4, 5, 6 transitions, so 6 emission lines...
