Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Electromagnetic (EM) waves
Concept:

An accelerating electric charge creates time-varying electric and magnetic fields that propagate through space.

Solution:

A stationary charge produces only an electric field. A charge moving at a constant velocity produces both static electric and magnetic fields.

However, when a charge accelerates, its electric and magnetic fields vary with time, producing self-sustaining electromagnetic ripples that travel outward through space as EM waves.

Why other options are incorrect:

  • Static fields cannot propagate as waves because they do not vary with time.

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.
