In a Fabry-Perot interferometer, the circular fringes formed are referred to as fringes of Correct Answer equal inclination

Explanation:

  • A classic Fabry–Perot interferometer is formed by two closely spaced, partially reflecting mirrors which form a resonant optical cavity with maximum optical transmission at wavelengths that are multiples of the mirror spacing, at small incident light angles.

Maximum Light Transmission Condition:

n λ = 2 w cos α

Where

n = an integer

w = width between the glass plate

λ = wavelength of light

  • The Fabry-Perot interferometer uses the phenomenon of multiple-beam interference that arises when light shines through a cavity bounded by two reflective parallel surfaces.
  • Each time the light encounters one of the surfaces, a portion of it is transmitted out, and the remaining part is reflected back.

So, In a Fabry-Perot interferometer, the circular fringes formed are referred to as fringes of equal inclination.
