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.
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.
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.
Are radio telescopes detect objects that optical telescopes cannot?
Yes, that is correct.
How light and radio telescopes are different?
Light telescopes, such as optical telescopes, focus on visible light to observe celestial objects, while radio telescopes detect radio waves emitted by these objects. The design of optical telescopes involves lenses or mirrors to collect and concentrate light, whereas radio telescopes use large parabolic dishes to capture and amplify radio signals. Additionally, optical telescopes are limited by atmospheric conditions and light pollution, while radio telescopes can operate effectively through clouds and at night. This leads to different applications and discoveries in astronomy for each type of telescope.

How radio telescopes differ from optical telescopes.?
Radio telescopes collect radio waves. Optical telescopes capture visible light waves.
Are optical telescopes much bigger then radio telescopes?
No they are not bigger then radio telescopes at all.

How do radio telescope different from optical telescope?
Radio telescopes collect radio waves. Optical telescopes capture visible light waves.
How do radio telescope operate?
As far as I know, there is no "optical radio telescope". There are, separately, optical telescopes (which work with visible light), and radio telescopes (which work with radio 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

How do optical telescopes and radio telescopes gather info about stars?
using radio waves it collects the data.
How are the telescopes Keck I and Keck II different from radio telescope?
They are optical telescopes.
Are radio telescopes detect objects that optical telescopes cannot?
Yes, that is correct.
