WebThe limit to the angular resolution of a telescope is set by diffraction. Diffraction by a circular aperture causes a point source of light to be surronded by a series of rings, the analogs to … WebNov 3, 2024 · The diffraction or aberration reduces the resolution of an instrument and often creates a blurred image. Diffraction is associated with the wave nature of light. Light interferes with itself when it passes through a lens and creates a ring-shaped diffraction pattern called the Airy pattern.
