Says which of a following transitions in an hydrogen atom represent emission of the longest wavelength.
00:05
So we have n is equal to 3.
00:07
That is n is an is across to 3, 2, n is equal to 4.
00:11
We have an is equal to 4, 2, n is equal to 2, we have n is equal to 3, 2, n is equal to 1, 2, n is equal to 1, 2, n is equal to 2, we have n is equal to 1, 2, and is of course to 4.

So this question is saying, which are the following transition represent emission.
00:35
So emission means you are going from i energy to low energy.
00:40
Okay? so you need to think about that first.
00:45
So which of this, first of all, kind of separates the ones that are emission? so three to four is excitation...
