The Spectrum

Page history last edited by PBworks 17 years, 6 months ago
    • Definition:

 

The Spectrum is an unusual 2-dimensional plot of a single compound depicting the components by another measure. It's a diagram of the colors of the rainbow used to see the patterns of gas and energy let off in the atmosphere. The Spectrum is the range of all possible electromagnetic radiation that an object emits, reflects and transmits. It is used to show and classify all possible electromagnetic frequencies.

 

 

Relation to Astronomy:

 

Almost all objects in the universe emit or reflect some sort of light. Every object's spectra is determined on the type of radiation coming off of the object (every radiation has it's own footprint). The Spectrum covers light from every different group of radiation including gamma rays, X-rays, Ultraviolet rays, Microwaves, Radio Waves, the Visible Spectrum and infrared. The spectrum shows the types of gases that are let off of stars, the sun, etc. It helps astronomers to break down each individual gas and to tell them apart. It also shows the radiation being let off from every object.

 

 

Also The elements absorb certain wavelengths of light and reflect the rest. this makes a code that astronomers can use to figure out what elements a star is made of.
