The smallest angle that can be resolved with a telescope is determined by the Rayleigh criterion, which states that the minimum resolvable angle (θ) is given by θ = 1.22 * (λ/D), where λ is the wavelength of light and D is the diameter of the telescope's aperture. This formula is crucial for understanding the limits of telescope performance. The discussion highlights the importance of aperture size in resolving fine details in astronomical observations.
