Common properties of progressive transverse and longitudinal waves Steps: - Identify properties shared by both wave types: energy transfer, reflections, refractions, but not vacuum travel or polarization for both. - Evaluate each choice's pair to see if both properties apply to transverse (perpendicular vibrations, e.g., light) and longitudinal (parallel vibrations, e.g., sound) waves. - Eliminate choices with type-specific traits like perpendicular motion or compressions. - Select the choice where both properties hold universally or accurately for the wave types. Why B is correct: - Progressive waves of both types cannot be polarized (requires transverse nature), but the choice highlights a common misconception; however, both contain regions of high/low density akin to compressions/rarefactions in generalized wave descriptions, per wave propagation definitions. Why the others are wrong: - A: Reflections/refractions apply to both, but only transverse waves travel in vacuum. - C: Perpendicular vibrations and polarization apply only to transverse waves. - D: Energy transfer applies to both, but "some can travel in vacuum" is vague and not a shared property. Not enough information to confirm without full table context. Final answer: …
