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.


Do Optical telescopes have poorer resolution than radio telescopes?

Not necessarily.


Why big telescopes?

Large telescopes have improved resolution over small telescopes and as such can gather clearer images of objects further away.


How can they improve an optical telescopes resolution?

i dont know and ask me again


How is resolution affected by the size of a telescopes mirror or lens?

The resolution is directly proportional to the diameter of the main mirror or lens. For instance, twice the diameter means twice the resolution.


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 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.


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.


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


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.


For a telescope in space above the distortion due to the Earth's atmosphere the angular resolution of the telescope is?

The angular resolution of a telescope in space above Earth's atmosphere is significantly improved compared to telescopes on the ground. With no atmospheric distortion, the telescope can achieve its diffraction limit, which is determined by the aperture size of the telescope and the wavelength of light. This allows for sharper, higher-resolution images of astronomical objects.


What is the main reason for positioning many radio telescopes across a large area?

To produce higher resolution images.
