I agree with you. It's impossible to read and takes 2 minutes to fully load.

Is there a relationship between K and L emission lines and wavelength of emission spectra? If so, this chart summarizes it nicely.

It isn't user friendly at all, I got that too, but it's useful if you know what you're looking for. For example, I put Na and narrowed the search to 500 and 540, and got only a few matches.


I don't know if there's a relationship between K and L and wavelength.

At this moment, I only need to know a few following elements' majority spectrum wavelength:

1) CO2
2) N2
3) O2
4) H2
5) He2

Could you please help me to find those wavelength as shown above?
Do you have any suggestions?
Thanks, to everyone very much for any suggestions (^v^)

Infrared radiation absorbed by and emitted by CO2 has a wavelength of 15 micrometers.

N2 has a wavelength 96 and 102

645 nm

I just spent 30 minutes looking for these, but kept finding contradicting results. I don't think I'd be doing you a favor finding these because I don't see them correct

Thank you very much for your time 
Thanks, to everyone very much for suggestions (^v^)

You're welcome, if you find accurate wavelength values, please share with the community

I would like to follow up this issue, referring to following image, does Moon's atmosphere scatter more red light to Earth during new moon (daytime)?



Does anyone have any suggestions?
Thanks, to everyone very much for any suggestions (^v^)

I don't think the moon's atmosphere is strong enough to have this effect on Earth.

Thanks, to everyone very much for suggestions (^v^)

Do you have access right on following reference materials?
Thanks, to everyone very much for any suggestions (^v^)

For the elements, the CRC Handbook of Chemistry and Physics
has a big table in the section "optical physics", not in "spectroscopy".

http://hbcponline.com/faces/contents/ContentsResults.xhtml#

That's exactly what you need, the spectroscopy numbers for those gases. Interestingly, the only database available is:

https://physics.nist.gov/PhysRefData/ASD/lines_form.html?

It's the only one referenced by other scientist. But I don't know how to use it correctly. Once I study it, and learn how to read it, I'll reply back. Also, if you figure it out before me, let us know.

I'll reply to the other topic later today, won't be home until tonight

Thanks you very much and I wait for your reply.

Furthermore, referring to following image, Earth's atmosphere contains main N2 and O2, when Sunlight shine to Earth's atmosphere, what color of light are reflected from Earth to Space? On the other words, based on nitrogen spectrum image, would nitrogen from atmosphere mainly reflect red and blue spectrum toward space? and would oxygen from atmosphere mainly reflect green and red spectrum toward space? 

Do you have any suggestions?
Thanks, to everyone very much for any suggestions (^v^)



Ref : https://www.atoptics.co.uk/highsky/auror3.htm

From space, earth appears blue:



Here's the way I see it. The BLUE (and violet) light in the sunlight is the highest frequency (of what we can see) and therefore has the littlest waves. These smaller waves happen to be around half the size of the red waves. When these SMALL waves of blue light pass through the earth's atmosphere, many of them eventually "crash into" the relatively LARGE atoms of Oxygen and Nitrogen. They tend to "bounce off" (are reflected or SCATTERED) and then they go all directions including sideways and down toward us.

A more scientific way of saying this is to say that the Oxygen and Nitrogen atoms are of a size that has a "natural vibration rate" (called frequency) that is closer to the rates of vibration of BLUE light. So the blue light can cause those atoms to start vibrating. The vibrating atoms then give off blue light when they stop vibrating, and that new blue light can go in any direction. (It's a little more complicated than that, but the general idea is correct.)

Referring to following video, it seems that for Balmer Series there are many elements dropping to n = 2 orbit, which release blue color wavelength.  When blue wavelength is scattering, it requires electrons to interact with 2nd orbits to absorb and radiate energy (blue color wavelength). That make Ocean looking blue from space.



Furthermore, for following orbits, they release infrared wavelength.
Paschen Series (3rd Orbit) - Infrared wavelength
Brackett Series (4th Orbit) - Infrared wavelength
Pfund Series (5th Orbit) - Infrared wavelength

It seems that color / wavelength are fixed based on absorb and radiate energy levels. so why apple is red? which orbit levels are related to absorb and radiate energy (red color wavelength)? is the distance between orbit levels fixed within N2 (Blue) and O2 (Yellow or Orange) structure?

Furthermore, when red color wavelength do not change any orbit levels within N2 or O2 atom, does red color wavelength just pass through atom without any interaction with atom's electrons?

Do you have any suggestions?

I would like to check H2O absorption spectrum and confirm on whether blue color from ocean is related to H2O absorption spectrum or not.

Thanks, to everyone very much for any suggestions (^v^)

When you know on how to use the reference, could you please also check on H2O absorption spectrum as well?

Thanks, to everyone very much for any suggestions (^v^)
