The ratio of intensities of two waves is 4:1. They are producing interference. The ratio of maximum and minimum intensities will be:
Correct answer: B. 3 : 1
- A. 4 : 7
- B. 3 : 1
- C. 5 : 3
- D. 6 : 2
Explanation
When two waves with intensity ratio of 4:1 interfere, they create a ratio of maximum to minimum intensities of 3:1. This is due to the constructive and destructive interference patterns that result from the superposition of the waves. Option B is correct as it reflects this ratio accurately. Options A, C, and D are incorrect as they do not represent the correct relationship between maximum and minimum intensities in this scenario.

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.
