i dont know and ask me again
Not necessarily.
yes
interferometers because charge-coupled devices are only used in optical telescopes
Radio telescopes collect radio waves. Optical telescopes capture visible light waves.
Yes, because it must be very large in order to attain the resolution of optical telescopes.
No they are not bigger then radio telescopes at all.
Ccd's and in large telescopes
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.
Optical telescopes.
They are optical telescopes.
Yes, that is correct.
* By making them bigger.* By compensating for atmospheric disturbance, with something called adaptive optics.
