Exactly the same way that an optical telescope gathers waves with wavelngths
shorter than radio waves:
Both the mirror of a reflecting telescope and the 'dish' of a radio telescope are
built to have the shape of a 'paraboloid' ... that's the solid shape you get when
you spin a parabola around its nose.
The paraboloid has the interesting geometric property that anything that comes
straight in, parallel to its axis ... whether it's bees, bullets, B-Bs, or electromagnetic
waves ... and bounces off the inside of the curve, all winds up at the same point,
called the "focus" of the paraboloid.
-- The focus is where the film, or the eyepiece, the CCD, or the spectrometer
of the reflecting telescope is placed. All the light that hits the whole mirror is
concentrated onto it.
-- The focus is where the radio receiver of the radio telescope is placed.
All the radio waves that hit the entire dish are concentrated onto it.
-- The focus is where the little LNB on the end of the arm that sticks out in front
of the TV dish on your neighbor's garage is placed. All the microwave waves
from the TV satellite that hit the entire dish are concentrated onto it.
What else can I help you with?
A device used to detect radio waves from space?
they use radio waves to pick up some what satellite images or existance of things in space
What instrument used to gather information by bouncing radio waves off their surface?
the instrument used to gather radio waves is a special dish called a parabolic dish
Why doesnt the surface of a radio telescope have to be as flawless as the surface of a mirror in an optical telescope?
The surface of a radio telescope doesn't have to be as flawless as the surface of an optical telescope because the radio telescope is collecting radio waves, something that will not be affected by faults in the glass. Optical telescopes, on the other hand, are collecting light, where faults in the surface can interfere with the image.
How is a radio telescope different from both a refracting and a reflecting telescope?
Well, its simple, there are two things that are in common.... both telescopes have a eye peice and a radio telescope doesnt.... theres more to it and the radio telescope looks way diffrent then the regular ones..... Wow! What a non-answer this person has given! For one thing, radio telescopes look more like satellite dishes than traditional telescopes. Rather than operating on the visible light spectrum as a reflecting or refracting telescope would, radio telescopes gather information from the infrared light spectrum - radiation waves. These radiation waves are collected to form a picture of whatever the radio telescope is looking at. I'm not a scientist; I'm not an astronomy student. I just did a little bit of research that the original answerer obviously didn't do.
Is the image produced by a radio telescope the same as the image produced by a optical telescope?
no you cant see image its appers in waves
How does a radio telescope gather data?
a radio telescope focuses the incoming radio waves on a antenna, which absorbs and transmits these waves to an amplifier, just like a radio antenna.
What telescope do astromers use to gather radio waves?
radiotelescope
What is the difference between a radio telescope and a light telescope?
radio telescope detects radio waves and a light telescope views light waves.
How do radio telescope different from optical telescope?
Radio telescopes collect radio waves. Optical telescopes capture visible light waves.
What is the most powerfull telescope?
The most powerfull type of telescope is the Radio telescope. Radio waves travel much further than light waves.
What telescope doesn't use mirrors or lenses to gather light?
A radio telescope.
How is a radio telescope different from a refracting telescope?
A radio telescope detects light in the form of radio waves and a refracting telescope detects light in the visible wavelengths
What can detect radio waves from objects in space?
A radio telescope.
What does a radio telescope measure?
it measure waves
What telescope detects radio waves?
Arecibo, VLA
A device used to detect radio waves from space?
they use radio waves to pick up some what satellite images or existance of things in space
What is a device used to detect radio waves from objects in space?
Radio Telescope
