Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: Violet
Concept:

Within the visible light band, photon energy correlates with the color spectrum sequence.

Formula:

$$ E = hf $$

Solution:

  • Recalling the spectrum ROYGBIV (Red, Orange, Yellow, Green, Blue, Indigo, Violet).


  • Frequency and energy increase as we move from Red toward Violet.


  • Violet sits at the extreme high-frequency end (\( \approx 750 \text{ THz} \)), giving its photons the highest individual energy.


Why other options are incorrect:

Red is the lowest energy. Blue and Green are moderate, falling strictly below Violet in energy.

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.
