In Young's double slit experiment using white light:
Correct answer: B. Alternate dark and bright light will be seen
- A. Coloured fringes will be obtained
- B. Alternate dark and bright light will be seen
- C. No interference fringes will be seen
- D. None of these
Explanation
In Young's double slit experiment using white light, when light passes through the two slits, it undergoes interference, resulting in alternating dark and bright fringes. This phenomenon is due to the different wavelengths of light interfering constructively and destructively. Therefore, Option B is correct. Options A, C, and D are incorrect as they do not accurately describe the behavior of white light in this experiment.

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.
