In an interference pattern
Correct answer: C. both dark and bright fringes are of equal width
- A. bright fringes are wider than dark fringes
- B. dark fringes are wider than bright fringes
- C. both dark and bright fringes are of equal width
- D. central fringes are dimmer than the outer fringes
Explanation
Explanation: In an interference pattern, both dark and bright fringes have the same width. The width of the fringes is determined by the angular separation between adjacent maxima or minima.

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.
