Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Matter waves
Concept:

According to quantum mechanics (specifically Louis de Broglie's hypothesis), all matter exhibits wave-like properties.

Solution:

  • When elementary particles (like electrons, protons, or neutrons) travel at high velocities, their wavelength becomes physically significant.


  • These are formally defined as Matter waves (or de Broglie waves).


  • Their wavelength is given by \( \lambda = \frac{h}{p} \), where \( p \) is the particle's momentum.


Why other options are incorrect:

Transverse and longitudinal are classifications of macroscopic mechanical or electromagnetic waves, not the quantum probability waves associated with moving elementary particles.

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.
