In order to get the interference of fight waves:
Correct answer: D. All of these
- A. The sources should be monochromatic
- B. The sources should be phase coherent
- C. The linear superposition should be applicable
- D. All of these
Explanation
The correct answer is Option D: All of these. Monochromatic sources ensure a single wavelength for interference, phase coherence maintains constant phase relationship for constructive interference, and linear superposition allows waves to combine to form the interference pattern. Options A, B, and C alone do not cover all the necessary conditions for achieving interference of light waves.

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.
