Question

State the explain Rayleigh's criterion

Answer 1

For a circular aperture, lens, or mirror, the Rayleigh criterion states that two images are just resolvable when the center of the diffraction pattern of one is directly over the first minimum of the diffraction pattern of the other.

Answer 2

Answer:

HEY MATE,

HERE'S YOUR ANSWER.

According to Rayleigh's criterion, for a circular aperture, lens, or mirror, the Rayleigh criterion states that two images are just resolvable when the center of the diffraction pattern of one is directly over the first minimum of the diffraction pattern of the other.

The Rayleigh criterion specifies the minimum separation between two light sources that may be resolved into distinct objects. When a point source, such as a star, is observed through a telescope with a circular aperture, the image is not a point source – it is a disk surrounded by a number of very faint rings.
