In Michelson interferometer, the fringes of equal inclination produced are called as- Correct Answer Haidinger's fringes

The correct answer is option 3) i.e. Haidinger's fringes.

CONCEPT:

  • Michelsons Interferometer: It is a device used to study the properties of interference of light waves.
    • The interferometer splits a beam of light such that one beam strikes a fixed mirror and the other beam strikes a movable mirror.
    • The beams after reflecting from the mirrors are brought back together to produce an interference pattern.
    • When light from an extended source falls on a thin film of an optically denser medium, fringes of equal inclinations are produced.
    • These fringes indicate the position where light interferes, emerging from a medium at an equal angle.

Additional Information

  • The experiment was known as the Michelson-Morley experiment but the fringes of equal inclination produced by the interferometer were called Haidinger's fringes.
