What else can I help you with?
When multiple radio telescopes are used for interferometry resolving power is most improved by increasing?
Increasing the distance between the two most widely separated radio telescopes has an enormous effect on resolution.
What is the advantage of placing two small radio telescopes 100 meters apart?
Placing two small radio telescopes 100 meters apart allows for interferometry, which enhances the overall resolution of the observations. This configuration effectively simulates a larger telescope with a diameter equal to the distance between the two dishes, enabling the detection of finer details in astronomical objects. Additionally, combining data from both telescopes improves sensitivity and signal quality, allowing for more accurate measurements of celestial phenomena.
Why do you use only two types of telescopes here on earth optical or radio telescopes?
Radiation other than light and radio waves hardly penetrates Earth's atmosphere.
What two phenomena that radio telescopes have revealed?
# Cosmic background radiation (remnants of the Big Bang). # Quasars.
Why do single dish radio telescopes have poor resolving power compared to optical telescopes of the same diameter?
Radio telescopes are generally much larger than optical telescopes for two reasons: First, the amount of radio radiation reaching Earth from space is tiny compared with optical wavelengths, so a large collecting area is essential. Second, the long wavelengths of radio waves mean that diffraction severely limits the resolution unless large instruments are used.

What is Data from multiple radio telescope is combined with?
Two or more radio telescopes!
What is interferometry?
Astronomers improved radio images by connecting telescopes. If two radio telescopes are separated by distance but are connected electronically, their signals can be combined using a computer. The resulting images are as good as if one telescope were used that was as big as the distance between the two. This method is called interferometry.
What are the two ways scientists explore space?
light telescopes and radio telescopes whether installed on earth or on space vehicles
Why do you use only two types of telescopes here on earth optical or radio telescopes?
Radiation other than light and radio waves hardly penetrates Earth's atmosphere.
What is the base line of a radio telescope array?
The distance between the two antennae that are the farthest apart is the baseline of a radio telescope array..

What devices uses radio waves?
Radio waves are used to help transmit signals between two devices.Some devices which use radio waves are:RadiosTelevisionsMobile (cell) phonesCordless telephonesNavigational devices (such as GPS and satellite tracking)RadarRadio-tuned clocks and watchesRadio telescopes
How far can you see with a radio telescope?
Radio telescopes can detect radio waves from celestial objects billions of light-years away, allowing scientists to observe phenomena such as quasars, pulsars, and the cosmic microwave background radiation. The distance at which a radio telescope can "see" depends on the strength of the signal emitted by the object being observed and the sensitivity of the telescope's receivers.
What use does a handheld cb radio have?
The Citizens Band radio is defined to be a short distance radio communications device. Its uses includes cheap and efficient talking between two stations without any interruptions.
What is the distance between two points called?
lengthThe distance between two points is called the displacement.
