select the correct answer. which statement is true of a wave thats propagating along the pavement and girders of a suspension bridge? a. the wave is mechanical, with particles vibrating in a direction that is parallel to that of the wave, forming compressions and rarefactions. b. the wave is electromagnetic, with particles vibrating in a direction that is parallel to that of the wave, forming compressions and rarefactions. c. the wave is mechanical, with particles vibrating in a direction that is perpendicular to that of the wave, forming crests and troughs. d. the wave is electromagnetic, with particles vibrating in a direction that is perpendicular to that of the wave, forming crests and troughs. e. the wave is mechanical, with particles vibrating in a direction that is perpendicular to that of the wave, forming compressions and rarefactions.

Answer

Brief Explanations:

A wave on a suspension - bridge is a mechanical wave as it requires a medium (the bridge structure) to propagate. In a mechanical wave on a string - like structure (such as the cables of a suspension bridge), the particles vibrate perpendicular to the direction of wave propagation, forming crests and troughs. Electromagnetic waves do not require a medium and are not relevant here. Compressions and rarefactions occur in longitudinal waves where particle vibration is parallel to wave propagation.

Answer:

C. The wave is mechanical, with particles vibrating in a direction that is perpendicular to that of the wave, forming crests and troughs.
