The ratio of intensities between point A and that of the central fringe is 0.853. The path difference between the two waves at point A will be:
Correct answer: C. λ/8
- A. λ/2
- B. λ/4
- C. λ/8
- D. λ
Explanation
The correct answer is Option C: λ/8. The path difference between the two waves at point A can be calculated using the intensity ratio formula. Since the intensity ratio is 0.853, this corresponds to a path difference of λ/8. Options A, B, and D can be ruled out based on this calculation.

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.
