The fringes in Michelson interferometer are formed due to
Correct answer: B. Interference
- A. Diffraction
- B. Interference
- C. Polarization
- D. None of these
Explanation
The correct answer is interference. In a Michelson interferometer, light from a single source is split into two beams, which travel different paths before being recombined. The slight path difference causes the light waves to interfere with each other, creating a pattern of bright and dark fringes. Diffraction, on the other hand, is related to light bending around obstacles, and polarization relates to the orientation of light waves, neither of which are responsible for the fringe formation here. Thus, the correct answer is interference, not diffraction, polarization, or 'none of these'.

About Optics
Light is studied through reflection, refraction, dispersion, interference, diffraction and polarization, linking ray behavior with its wave nature. Questions may involve mirrors, lenses, optical instruments, refractive index and image formation, while geometrical optics deals with rays and wave optics explains effects such as interference and diffraction.
