Propolis Cognitive Error Autopsy

Official Correct Choice:
Option D: Lowest point of the wave
Concept:

Transverse waves possess defining geometric characteristics representing maximum displacements.

Solution:

  • As particles oscillate perpendicular to the wave direction, they reach positive and negative extremes.


  • The crest is the maximum positive displacement (highest point).


  • The trough is the maximum negative displacement, representing the lowest point of the wave profile.


Why other options are incorrect:

Option C describes a crest. Options A and B represent scalar wave properties, not physical locations on the wave geometry.

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.
