What else can I help you with?
In principle the dish of a radio telescope operates in the same manner as the?
Concave mirror of a reflecting telescope
What receives radio waves from space objects such as quasars?
Radio telescope, usually a microwave dish with a movable parabolic reflector.
When was the radio telescope first made?
The first radio antenna used to identify an astronomical radio source was one built by Karl Jansky, an engineer with Bell Telephone Laboratories, in 1931. Jansky was assigned the job of identifying sources of static that might interfere with radio telephone service.
Radio waves strike a large curved what in a radio telescope?
Radio waves strike a large curved dish in a radio telescope. This dish, often parabolic in shape, collects and focuses the incoming radio signals onto a receiver located at the focal point. The design allows for efficient capture of weak radio signals from space, enabling astronomers to study celestial objects and phenomena.
Arecibo radio telescope is laid out like which optical telescope design?
The Arecibo radio telescope is not laid out like any specific optical telescope design. It is a unique design called an "active spherical reflector" where the dish itself is spherical in shape and fixed in position. This design allows for a large collecting area and a high sensitivity to radio signals.
Does a radio telescope have a dish reflector?
Yes.
Which instrument uses a dish antenna?
radio telescope does.
In principle the dish of a radio telescope operates in the same manner as the?
Concave mirror of a reflecting telescope
Why the radio telescope dish is not solid?
Nothing is "solid"; there are always holes, gaps in matter. An object APPEARS solid when the wavelength of the radiation used is longer than the size of the gaps or holes. The radio waves that radio telescopes use are several millimeters long, and the mesh in a radio telescope dish is smaller than that - so to a radio wave, the dish looks solid.

In a radio telescope radio waves strike a large curved?
In a radio telescope, radio waves strike a large curved dish, which reflects and focuses the waves onto a receiver at the focal point. The receiver then converts the radio waves into electrical signals that can be processed and analyzed by astronomers. This allows scientists to study celestial objects and phenomena in the radio frequency range.
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 the name for the biggest telescope?
Currently the largest optical telescope is "The Great Canary Telescope" (Gran Telescopio Canarias) in Spain, it has an apeture of 10.4 metres. There is an optical telescope under construction in Chilie that when completed will have an apeture of 21.4 metres, called the Giant Magellan Telescope. The largest single dish apeture radio telescope is the Arecibo Radio Telescope in Puerto Rico which is 305 metres.
How does a radio telescope gather radio waves?
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 is the difference between a radio telescope and a light telescope?
radio telescope detects radio waves and a light telescope views light waves.
