Do Optical telescopes have poorer resolution than radio telescopes?
Not necessarily.
Distance between two radio telescopes?
The distance between two radio telescopes is important for interferometry, a technique used to combine signals from multiple telescopes to improve resolution and sensitivity. By measuring the time delay between the signals received at each telescope, scientists can determine the distance between them and use this information to create detailed images of celestial objects.
Do Radio telescopes have poorer angular resolution than optical telescopes because radio waves have a much longer wavelength than optical waves?
Yes, that's correct. The longer wavelengths of radio waves mean that radio telescopes have poorer angular resolution compared to optical telescopes. This is because resolving power is inversely proportional to the wavelength of the electromagnetic waves being observed.
Radio telescopes are often connected together to do interferometry What is the primary problem overcome by radio interferometry?
The primary problem overcome by radio interferometry is the limited resolution of individual telescopes. By combining signals from multiple telescopes, interferometry creates a virtual telescope with a larger diameter, which improves the resolution and allows astronomers to see finer details in the radio sources being observed.
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.
Do Optical telescopes have poorer resolution than radio telescopes?
Not necessarily.
What is the main reason for using several radio telescopes together as an interferometer and how does this technique enhance the resolution and sensitivity of astronomical observations?
Using several radio telescopes together as an interferometer allows for a larger effective aperture, which enhances the resolution and sensitivity of astronomical observations. This technique combines the signals from multiple telescopes to create a virtual telescope with a resolution equivalent to a single dish with a diameter equal to the farthest separation between the telescopes. This results in sharper images and the ability to detect fainter signals from celestial objects.

Does an optical telescope and a radio telescope of the same size have the same angular resolution?
No, they do not. The angular resolution of a telescope is determined by the wavelength of the radiation it is measuring and its diameter. Since optical telescopes detect shorter wavelengths than radio telescopes, they generally have better angular resolution for viewing fine details.
What is the main reason for positioning many radio telescopes across a large area?
To produce higher resolution images.
How radio telescopes differ from optical telescopes.?
Radio telescopes collect radio waves. Optical telescopes capture visible light waves.
The resolution of radio telescopes has been improved by what spectrographs charge-coupled devices photometers or interferometers?
interferometers because charge-coupled devices are only used in optical telescopes
Are optical telescopes much bigger then radio telescopes?
No they are not bigger then radio telescopes at all.
What is the purpose of interferometry?
Interferometry is used to combine signals from multiple telescopes to create a single image with higher resolution. This technique enables astronomers to study fine details of astronomical objects that would not be possible with a single telescope of the same size. It is commonly used in radio astronomy and optical astronomy.
