The Airy disk is a phenomenon related to:
Show answer and explanation
Correct answer: The diffraction pattern of light passing through a circular aperture
When light passes through a lens, it diffracts and forms a central spot called an Airy disk. Resolution is determined by the ability to distinguish two overlapping Airy disks as separate points.
