WebMay 21, 2024 · Baron Rayleigh based the observation on optical experiments on diffraction patterns caused by light transmission through slits. This criterion plays an important role in seismic resolution. It states … 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.
