In order to collectenough radio photons to detect a signal, the radio dishes must be very large. An optical telescope is a telescope that gathers and focuses light, mainly from the visible part of the electromagnetic spectrum, to create a magnified image for direct view, or to make a photograph, or to collect data through electronic image sensors. There are three primary types of optical telescope: refractors, which use lenses reflectors, which use mirrors catadioptric telescopes, which combine lenses and mirrors A telescope's ability to resolve small detail is directly At the present comparison of optical and radio telescopes that are completely finished or are under construction the largest optical scope is the E-ELT with a diameter of 39.3 meters; the largest radio telescope is the Chinese 500 meter diameter s Angular resolution describes the ability of any image-forming device such as an optical or radio telescope, a microscope, a camera, or an eye, to distinguish small details of an object, thereby making it a major determinant of image resolution. It is used in optics applied to light waves, in antenna theory applied to radio waves, and in acoustics applied to sound waves.

They don't need finely polished mirrors and they are much, much bigger in size. So. There are many differences between optical and radio telescopes The two main differences are the design of the telescopes and the results optical telescopes usually stand on three legs and have a tube-like apperance radio telescopes are made up of a parabolic dish, a recorder computer and an amplifier. What is Optical Astronomy and Radio Astronomy?

There are two main types of Many celestial objects, such as pulsars or active galaxies (like quasars), produce radio-frequency radiation and so are best "visible" or even only visible in the Earth Based Telescopes – Radio Telescopes. The stars, galaxies and other astronomical objects emit radio waves. These radio waves can be detected on Earth The resolution, θ of a telescope depends on its aperture, or mirror/dish diameter, best radio telescopes have dishes that are 70-100m (or even larger) in diameter. At optical/infrared wavelengths, telescopes usually comprise of a 9 Oct 2020 They could harm not just optical, but radio astronomy. by excluding them from a radio quiet zone or siting telescopes in remote areas.

Radio telescopes, like its name suggests, uses radio waves from distant celestial bodies in order to create an image. Every astronomical body gives off waves, the radio telescopes reads these and deciphers the radio noise into its corresponding radio range of the light spectrum. tion of telescopes. The future large optical telescopes like TMT, are likely to ﬁll the major gap that is left by the current generation of optical telescopes. 2.
