In a double-slit experiment, if one of the two slits is covered then
Correct answer: A. No interference fringes are observed
- A. No interference fringes are observed
- B. No diffraction fringes are observed
- C. No fringes are observed
- D. Interference pattern is not disturbed
Explanation
Explanation: In a double-slit experiment, when one of the two slits is covered, the interference pattern is disrupted, and no interference fringes are observed. The double-slit interference pattern relies on both slits being open to create the interference pattern.

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.
