Question

what is the limit of resolution of reflecting telescope?​

Answer 1

Answer:

The resolution of a telescope is its ability to separate two point sources into separate images. Under ideal conditions, such as above the atmosphere where there is no turbulence (seeing), the resolving power is limited by diffraction effects.

Answer 2

Explanation:

it gives frindges

where λ is the wavelength of the observed radiation, and D is the diameter of the telescope's objective. The Resulting R is in radians. For example, in the case of yellow light with a wavelength of 580 nm, for a resolution of 0.1 arc second, we need D=1.2 m.
