Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Stationary wave
Concept:

Waves are characterized by whether they transport energy across physical distances.

Solution:

  • A progressive (or traveling) wave continuously carries energy outward from a source.


  • A stationary (standing) wave is created when two identical waves traveling in opposite directions overlap. Their opposing energy flows perfectly cancel each other out macroscopically.


  • Consequently, the energy is trapped, oscillating purely between potential and kinetic forms within discrete loops. There is zero net transfer of energy across any node.


Why other options are incorrect:

Longitudinal, transverse, and progressive waves all actively transport energy from point A to point B.

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.
