Thanks for the Welcome!!
Oh my god, I feel so stupid. I already know that!
Good lesson for others if they do not want to study super ineffectively and look dumber than they are:
Do not study when you have not slept for the last 48 hours.I know and understand everything you just replied. One thing I was confused about last night was why it showed us 4 emission/absorption lines for hydrogen. Because I earlier thought that the amount of lines equaled to the amount of electron levels for the atom. (I was like "Hydrogen has one electron if not an ion = should have only one line??") But now I know that it still means that, but it also means the amount of possible levels the electron can reach without leaving the atom. So 4 is the amount of lines and therefor the electron can reach the fourth shell (n-shell) if it recieves enough energy for that orbital transition. More energy recieved will lead to the recieving the level of energy required for ionization.
Okay, so the other thing I was confused about was why it would emit red light, I percieved the K shell to have connections with the line furthest to the left in the screenshot I provided. And that the line in the red light was the n- shell.
Well, I now know thanks to Wikipedia, searching electromagnetic spectrum, that I was looking on it the wrong way.
Keep this in mind:
If Energy is high, Wavelength must be low and vice versa. Because h and c are constants.So looking at the electromagnetic spectrum in the visible class, we can see that red light has a long wavelength, therefor energy must be low. And the ultraviolet part has shorther wavelengths = more energy.
And as you mentioned, just like potential energy for physical objects being lifted above the ground it is at a higher energy level the further away it is from the attracting force (center of the earth, gravity) which in our case is the nucleus. So that means Red light - K shell, "Green" light - L shell, and so on.
Therefor an electron moving from L to K emits red light (it was one energy level transition = first energy level is red light). (I have read more about this aswell, discrete values for energy levels, or maybe I should say "light is quantized into packets of energy" and these values are countable etc)
Sorry for my bad english and if I wrote a sloppy essay, just thought if some else is asking the same question as me they might find my post useful.
Thank you again Enthalpy, you guided me into the right path of solving this problem.
