Question

Write two differences between haidinger fringes and fizeau fringes

Answer 1

Fizeau fringes. Interferencefringes of monochromatic light from interference in a geometrical situation other than plane parallel plates. Also known as fringes of equal thickness. Interferencefringes in light from a Fizeauinterferometer.


Haidinger fringes are fringes localized at infinity. Also known as fringes of equal inclination, these fringes result when light from an extended source falls on a thin film made of an optically densermedium. These fringes indicate the positions where light interferes, emerging from the medium at an equal angle 

Answer 2

Answer:

Haidinger fringes: Haidinger fringes are defined as apparent dark and bright fringes created by the interference of coherent and monochromatic lights.

Fizeau fringes: However, Fizeau fringes can be generated when a very thin air layer separates the surfaces; this type of pattern can take many different forms.

Explanation:

Fringes of Fizeau: monochromatic light interference fringes caused by interference in a condition other than planar parallel plates. also referred to as equal-thickness fringes. Light from a Fizeau interferometer has interference fringes.

Haidinger fringes: Localized at infinity, Haidinger fringes are fringes. These fringes, often referred to as fringes of equal inclination, happen when light from a long source strikes a thin film made of an optically dense substance. These fringes, which emerge from the medium at an equal angle, show the locations where light interferes.
