Separating light into its spectrum of colors is a characteristic of a cheap,
poor quality telescope. One reason for the high cost of perfect optics in a
research-grade telescope is the cost of lens material that has the same
identical effect on light of all colors, and does notproduce a spectrum.
That's one of the great advantages of the reflecting telescope . . . the light
only reflects off of the surface of the mirror, and doesn't pass through it,
so any effect the mirror may have on light passing through it is completely
unimportant.
The telescope must not produce a spectrum. When the astronomer wants
a spectrum, he uses an external device to produce it.
What else can I help you with?
Does a prism separate light into only the visible spectrum or the entire spectrum?
A prism separates light into the visible spectrum, which includes the colors of the rainbow. It does not separate light into the entire electromagnetic spectrum, which ranges from gamma rays to radio waves.
How does light separate into the colors of the visible spectrum?
When light goes through a prism, it separates into a rainbow.
Which region of the electromagnetic spectrum can easily reach a telescope on the earth's surface?
Visible light.
How does a radio telescope see objects which are too dim for an ordinary telescope?
Radio Telescope observe light of a different wavelength then optical light. Radio waves have a longer wavelength then visible light. Some interstellar objects barley emit any light in the visible spectrum but emit a significant amount of radiation in the radio spectrum. Radio telescopes enable us to view objects which emit in the radio spectrum.
What kinda light is a mixture of all visible wavelengths of the spectrum?
White light is a mixture of all visible wavelengths of the spectrum. When white light passes through a prism, it separates into its constituent colors creating a rainbow effect.
What might you observe with a radio telescope that you couldn't observe with an optical telescope?
Object that only shine with radio waves and not in the visible spectrum an object hidden by dust that block visible light.
How is white light and visible spectrum alike?
White light contains all the colors of the visible spectrum. When white light passes through a prism or water droplets creating a rainbow, it separates into the different colors of the visible spectrum: red, orange, yellow, green, blue, indigo, and violet.
When you see a rainbow in the sky or in the mist of a waterfall you are seeing all the wavelengths of visible light Which process separates the different components of the visible light spectrum so?
refraction
How is an optical telescope different from the others?
An optical telescope focuses and concentrates visible light; radio telescopes focus and concentrate electromagnetic radiation (which means, "light") in the radio part of the spectrum.
Why can radio telescope can see things that a telescope that detect visible light cant?
-- The source may be one that emits electromagnetic energy in the radio portion of the spectrum but little or no visible light. -- There may be material in the way, such as dust or gas, that absorbs visible light but doesn't absorb radio energy.
White light consists of what?
This light consists of all the colors of the rainbow, which are in the visible spectrum of electromagnetic waves. White light consists of: violet, indigo, blue, green, yellow, orange, and red, in the order from the lower end of the electromagnetic spectrum of visible light to the higher end of the spectrum.
Can you study visible light using a radio telescope explain your answer?
No, a radio telescope is designed to detect radio waves, which have much longer wavelengths than visible light. Visible light cannot be studied using a radio telescope as it operates in a different part of the electromagnetic spectrum. To study visible light, astronomers typically use optical telescopes.
