A spectroscope behaves in a similar manner to that of a prism.
Except that instead of the light passing through a prism, it is reflected from a special surface called an optical grating. Or a diffraction grating.
A diffraction grating has a multitude of fine lines drawn across it to produce a saw-tooth pattern. One face of the saw tooth pattern is silvered so it reflects light.
(This is the pattern you see on one side of a CD.)
The lines may be as finely spaced 5000 lines/mm.
These reflection gratings (there can be transmission ones as well ) split the light beam into all its component colours.
So if the light from a remote star (well they are mostly remote aren't they?) can be split up by the grating, and analysed for the spectral lines of particular elements. Beats travelling there!
The 'rainbow' pattern you see on a CD will show this effect for similar reasons.
If you angle the light from a fluorescent light on your CD, you'll find that it is NOT a continuous rainbow spectrum. It will have a green area, and a red area, etc, but with fairly sharp boundaries between the colours.
These are the colours given off by the phosphors in the tube. If you try a tube with a different colour, you'll see a different pattern. And if you try some different CDs, you'll also see different patterns.

Who was the first scientist to study plankton?
The fist scientist to study plankton was Victor Hanson.
What will a scientist never do in an observational study?
In an observational study, a scientist will never draw attention to himself or herself. They will also not attempt to randomize a study.
What do life scientist study now?
The answer is your mom
Scientists who study anatomy?
A scientist who studies anatomy is called a anatomist.
How do scientist develop scientific explanations about subjects that are impossible to study through controlled experiments?
Scientist use models
What do scientists study to determine shifts in wavelength of light?
It is a spectrum
Who is the scientist who used a prism to study light?
isaac newton
How are wavelengths of light detected?
Spectroscopy originated through the study of visible light dispersed by a prism according to its wavelength. An instrument called a spectrometer is used in spectroscopy for producing spectral lines and measuring their wavelengths and intensities.
How do scientist study invisible radiation from objects in space?
They study visible light by using optical telescopes.
What kind of scientist studies the spectrum?
If you are meaning the light spectrum, Physicists study all forms of light and waves and what they do.
How does the scientist study volcanoes?
You go inside the volcano and light it up and see if it really explodes.
What kind of scientist are there?
Paleontologist-studys fossils of once living organisms Geologist-studys rocks Geochemist-studys the creation of rocks Volcanologist-studys volcanoes Entomologist-studys insects Biologist-studys living organisms Botany-study of plants Zoology-study of animals Bacteriology-study of bacteria Ecology-study of relationships among organism & their physical environments Histology-study of tissues which make up the body Mycology-study of fungi Morphology-a branch of biology that deals with the forms and structure of plants & animals Photochemistry-study of chemical changes involving light Physics-study of matter & energy
What is a physicist scientist?
A scientist that studies Physics (Fizz-zicks) which is the study of all physical things e.g matter, energy and light :) Hope this helped
How you can become as a scientist?
You have to study and study to become a scientist. you have to do experaments your self to see if you are a natural scientist.
What section of the electromagnetic spectrum would you use to study waves that humans can see?
The wavelength of the electromagnetic visible to the naked human eye is light. Light has wavelengths of 460 to 760 nanometers.
Why do we study science and scientist?
why important to study about science and scientist? p;
One reason that infrared wavelengths are difficult to study is that?
most infrared wavelengths are absorbed by Earth's atmosphere
