What is Emission and Absorption Spectra all about?
« on: September 22, 2007, 11:05:27 AM »
I have recently studied about this, and not much went to the back of the head! Anything that could make the study of Emmsion and Absorption Spectra, as well, Line or Hydrogen Spectra?

Any help to balancing of Redox Reactions other than the Ion-electron Method, or Half-reaction Method, would be really helpful.

Thanks

Dear Haunted Chmist,

In the moment I will answer you only the first part of your Question.

Let’s draw a ”Picture”:
As you may know, the sun is sending some Light to Earth, that’s called “Emission”. At a rainy day you may see a “Rain-bow” and if you measure and record the Intensity of each Colour, you have generated a so called ”Emission-Spectrum”.
Of course! You don’t need a rain, to record the ”Emission-Spectrum” from our sun, a device sometimes called a “Spectrometer”, would do a more precise job.
On the other side, from every subject/body that is hit by sun-light you can recognise a Colour, too.
This is because the subject/body is “extracting” some kind of the Light, and the remaining light is finally received by your Eyes. This Extraction is also called “Absorption” of Light, and if you now analyse the remaining Light with the “Spectrometer”, and now record, how much Light is missing, you generate a so called “Absorption-Spectrum”.

How Spectrometers work, and how you can calculate with Light and what for, you can read for Example on the Page:
There are a Lot of related Pages on the same Site, too.
A Lot of answers you can also find on the Page:


I hope this may be of any help for your start.

Good Luck!
