Concept:Polarization is the phenomenon wherein a wave's oscillations are physically restricted to a single defined plane.
Solution:- Transverse waves (like light or ripples) possess oscillations perpendicular to their direction of travel. Because there are infinite 360-degree perpendicular angles, a filter can be applied to "polarize" or isolate just one specific angle/plane.
- Longitudinal waves (like sound) oscillate parallel to their travel path. Because there is only one geometric dimension parallel to a line, they cannot be filtered into different planes. They are inherently un-polarizable.
Why other options are incorrect:Sound (Option C) and longitudinal waves (Option A) are strictly un-polarizable. Mechanical waves (Option B) is too broad, as it includes both polarizable (water) and un-polarizable (sound) waves.
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.
