In a Young's double-slit experiment, the center of a bright fringe occurs wherever waves from the slits differ in phase by a multiple of:
Correct answer: C. 2π
- A. 3π/4
- B. π
- C. 2π
- D. π/2
Explanation
In a Young's double-slit experiment, the central bright fringe (zeroth-order fringe) occurs when waves from the two slits have a path difference corresponding to a multiple of the wavelength. This results in a phase difference of 2π or a multiple of 2π.

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.
