Formula Used
Resolving Power = Aperture of Objective/(1.22*Wavelength)
RP = a/(1.22*λ)
This formula uses 3 Variables
Variables Used
Resolving Power - The resolving power of an objective lens is measured by its ability to differentiate two lines or points in an object.
Aperture of Objective - Aperture of Objective is the measure of its ability to gather light and to resolve fine specimen detail while working at a fixed object distance.
Wavelength - (Measured in Meter) - Wavelength is the distance between identical points (adjacent crests) in the adjacent cycles of a waveform signal propagated in space or along a wire.
STEP 1: Convert Input(s) to Base Unit

## How is resolving power of a telescope calculated ?

In telescopes, very close objects such as binary stars or individual stars of galaxies subtend very small angles on the telescope. To resolve them we need very large apertures. We can use Rayleigh’s to determine the resolving power. R.P. = a / 1.22λ where a is the aperture of the objective and λ is the wavelength of the light used to illuminate the object.

## How to Calculate Resolving Power of Telescope?

Resolving Power of Telescope calculator uses Resolving Power = Aperture of Objective/(1.22*Wavelength) to calculate the Resolving Power, Resolving power of telescope is the inverse of the smallest angular separations between two distant objects, whose images are separated in the telescope. Resolving Power is denoted by RP symbol.
