When photons bounce off a polished surface?

The process occurring when photons bounce off a polished surface is called: Reflection.

Which telescope design is subject to chromatic aberration?

Advantages of reflecting telescope over a refracting telescope: A refracting telescope uses a lens, which bends red light more than blue light, so the image has color halos. This is called chromatic aberration. A reflecting telescope reflects all wavelengths of light at the same angle, so there are no color halos.

What problem do refractor telescopes have that reflectors don t?

What problem do refractor telescopes have that reflectors don’t? This design involves only one optical surface, a concave mirror. the elimination of chromatic aberration.

Why are most large telescopes reflectors not refractors?

Why are most large telescopes reflectors, not refractors? Reflectors do not suffer from chromatic aberration like refractors do.

What is one advantage of large telescopes over small ones?

It’s much easier to resolve small storms in Jupiter’s atmosphere, bright knots in distant galaxies, or tiny lunar craterlets through a large telescope than through a small one. The other major advantage of a large telescope is light-gathering power.

What is the main reason that ultraviolet astronomy must be done in space?

What is the main reason that ultraviolet astronomy must be done in space? Earth’s atmosphere absorbs most ultraviolet wavelengths.

Which type of telescope has the simplest light path?

A refracting telescope such as a Keplerian or Galilean telescope has the simplest light path as the light enters through the lens in the aperture, down the tube of the telescope, and then out through the lens in the eyepiece.

What is the resolving power of the telescope quizlet?

resolution. What is the resolution of a telescope? its ability to distinguish two adjacent objects close together in the sky. Only $2.99/month.

Which of the following is an advantage of reflector telescopes over refractor telescopes?

Reflecting telescopes have many advantages over refracting telescopes. Mirrors don’t cause chromatic aberration and they are easier and cheaper to build large. The are also easier to mount because the back of the mirror can be used to attach to the mount. Different reflectors use different shapes of mirrors.

Are refractors better than reflectors?

Refractor telescopes use specialized lenses that make them a favorite for deep space objects like galaxies and nebulae. Reflector telescopes are more popular with larger and brighter objects like the Moon and planets because they use mirrors that provide more sensitivity to all wavelengths.

Do astronomers use reflecting or refracting telescopes?

A refractor uses lenses within a tube to refract (bend) light. It’s the type of long telescope which you might imagine old-time astronomers, like Galileo, using. Reflectors, on the other hand, use mirrors instead of lenses to reflect light. Most modern observatories use reflectors because their telescopes are so huge.

What is true of a blackbody?

What is true of a blackbody? Its energy peaks at he wavelength determined by its temperature. If a light source is moving away from you near the speed of light it will appear.

Why do telescopes use mirrors?

Most telescopes, and all large telescopes, work by using curved mirrors to gather and focus light from the night sky. The first telescopes focused light by using pieces of curved, clear glass, called lenses. Because mirrors are lighter, and they are easier than lenses to make perfectly smooth.

What are the advantages of a refracting telescope?


  • Superior revolving power per inch of aperture.
  • Superior performance in inferior conditions – image steadier.
  • Not reflections or interruption of light path.
  • Near permanent optical alignment – minimum maintanance.
  • Long focal ratios can mean use of longer focus, simplier, eyepieces.

What is the difference between a refractor and a reflector telescope?

The main difference between refractor and reflector telescope is that the refractor uses optical lenses, and the reflector telescope uses mirrors.
