Do Radio telescopes have poorer angular resolution than optical telescopes because radio waves have a much longer wavelength than optical waves?
yes
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.
Can you study visible light using a radio telescope explain your answer?
Yes, because it must be very large in order to attain the resolution of optical telescopes.
In what ways are radio telescopes better than optical telescopes?
Both types of telescope collect and focus electromagnetic radiation for observational purposes, the difference is their band of observed frequencies. Radio telescopes are used for the radio frequencies ( ~3km - ~30cm) while optical telescopes are used for frequencies closer to visible light ( ~0.7μm - ~0.4μm). Optical telescopes may also be able to detect infrared and ultraviolet light.
Do Radio telescopes have poorer angular resolution than optical telescopes because radio waves have a much longer wavelength than optical waves?
yes
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.
What can radio telescopes do that optical telescopes cant?
No. The gain of the antenna ... which translates directly into angular resolution ... depends on the wavelength (frequency) of operation.The 2.5 meter optical parabolic reflector (telescope) on Mt. Wilson is a titan. 2.5 meter parabolic radio antennas are routinely used in intercity microwave communication but would be quite useless for serious radio-astronomy, as they are such shrimps at radio wavelengths.
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.
