In Young's double-slit experiment, fringes are very close to each other. How can we increase the distance between fringes?
Correct answer: B. By increasing the distance from slits to the screen
- A. By increasing the distance between light source and slits
- B. By increasing the distance from slits to the screen
- C. By increasing the distance between slits
- D. By increasing the frequency of light
Explanation
The fringe separation is directly proportional to the distance between the double-slit and the screen where the interference pattern is observed. By increasing this distance, you will increase the distance between fringes on the screen.

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.
