Solution
Correct Answer:
λ D/d
In Young's Double Slit Experiment (YDSE), light from two coherent sources interferes to form a pattern on a screen.
- Fringe Width (β): The separation between two consecutive bright (or dark) fringes. β=dλD where λ is the wavelength, D is the distance to the screen, and d is the distance between the two slits.
This easy difficulty physics question is from the chapter optics, covering the topic of young's double slit. It appeared in the 2025 exam.
