When the crest of one wave falls over the trough of the other wave, this phenomenon is known as
Correct answer: C. destructive interference
- A. polarization
- B. constructive interference
- C. destructive interference
- D. diffraction
Explanation
Explanation: Destructive interference occurs when the crest of one wave coincides with the trough of another wave. This results in a reduction or cancellation of the overall amplitude at that point.

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.
