Concept:The Principle of Superposition is the fundamental law governing interference in linear wave systems.
Solution:- When two or more physical waves travel through the exact same medium simultaneously, they do not destroy or bounce off each other.
- Instead, at the exact point where they overlap, the momentary displacement of the medium is determined simply by algebraically adding the displacements of the individual waves.
- Therefore, the resultant amplitude is the mathematical sum of the amplitudes of the individual wave components at that specific instant in time.
Why other options are incorrect:Waves sum up; they do not multiply (Option B/C). The resultant is only zero (Option A) during perfect destructive interference, not "always".
Quality & Fidelity Assurance:
Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
