WebJan 25, 2024 · Therefore, we need large apertures to improve the resolving power of a telescope. We can prove this using Rayleigh’s criterion. The resolving power for a telescope is inversely proportional to the angular separation between two distant objects. Rayleigh’s formula is generally used for evaluating the resolving power of the telescope. WebApr 2, 2016 · The Attempt at a Solution. First, I substituted in λ 1 and λ 2 into Rayleigh and assumed they would have an equal aperture diameter, giving an equation that looks like . Of course this left two unknown values of θ. So, I then attempted to use the resolving power formula using the two wavelengths. I calculated R to be 1276.25.
