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.

Optical telescopes work fine during the day; it's just that the sunlight diffused throughout the atmosphere will "drown out" most of the stars. We can use optical telescopes to observe the Moon or the brighter planets like Jupiter or Venus.

Radio telescopes don't experience quite the same level of radio "noise" during the daytime unless the telescope is pointed pretty close to the Sun.

Radio telescopes pick up radio waves whereas Optical telescopes use light waves, so Radio telescopes show us things we cannot see with the naked eye or with optical telescopes.

yes


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.


What other kinds of radiation are detected by telescopes?

Researchers use all of these: -- optical telescopes -- radio telescopes -- x-ray telescopes -- infra-red telescopes -- ultraviolet telescopes
