At the point where the displacement of two waves cancels each other's effect. The path difference is an odd integral multiple of half of the wavelength. This effect is known as:
Correct answer: B. Destructive interference
- A. Constructive interference
- B. Destructive interference
- C. Stationary interference
- D. Simple interference
Explanation
Destructive interference occurs when waves come together so that they completely cancel each other out and when the path difference between the two waves is an odd integral multiple of half the wavelength of the wave.So the correct option is B.

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.
