If Young's Double-Slit Experiment (YDSE) is shifted into the water, then fringe spacing:
Correct answer: A. Will decrease
- A. Will decrease
- B. Will increase
- C. Will remain the same
- D. Will disappear
Explanation
The correct option is A because The fringe spacing in Young's Double-Slit Experiment is given by λD/d , where λ is the wavelength, D is the distance between the slits and the screen, and d is the distance between the slits. When YDSE is shifted into water, the wavelength (λ) decreases due to the change in the medium, leading to a decrease in fringe spacing.

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.
