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 else can I help you with?
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.
Which telescope optical or X-ray would have higher resolving power for the same aperture?
X-ray telescopes generally have higher resolving power compared to optical telescopes for the same aperture size. This is because X-rays have much shorter wavelengths than visible light, allowing for finer detail to be resolved. However, achieving high resolution in X-ray astronomy is more complex due to the need for specialized focusing techniques, such as grazing incidence mirrors. Ultimately, while both types of telescopes benefit from larger apertures, the inherent properties of X-rays lend themselves to greater resolving capabilities.
What and where are the largest optical telescopes in use today?
The largest optical telescope in use today is the Gran Telescopio Canarias (GTC) located at the Roque de los Muchachos Observatory in La Palma, Canary Islands. It has a primary mirror diameter of 10.4 meters (34 feet). Another large optical telescope is the Keck Observatory in Hawaii with two telescopes, each with a primary mirror diameter of 10 meters (33 feet).
Do Optical telescopes have poorer resolution than radio telescopes?
Not necessarily.
Are radio telescopes detect objects that optical telescopes cannot?
Yes, that is correct.

What three properties do optical telescopes have aid astronomers?
1) light-gethering power, 2) resolving power, and 3) magnifying power
How radio telescopes differ from optical telescopes.?
Radio telescopes collect radio waves. Optical telescopes capture visible light waves.

What is catadioptric telescope?
Basically, the catadioptric telescope is just one of the 3 main types of the optical telescopes.The other 2 main types of optical telescopes are the refracting telescopes and the reflecting telescopes.

beams of light
What limits the power of an optical telescopes?
aperture
