Which statement is true of a wave that’s propagating along the pavement and girders of a suspension bridge? the wave is mechanical, with particles vibrating in a direction that is parallel to that of the wave, forming compressions and rarefactions. the wave is electromagnetic, with particles vibrating in a direction that is parallel to that of the wave, forming compressions and rarefactions. the wave is mechanical, with particles vibrating in a direction that is perpendicular to that of the wave, forming crests and troughs. the wave is electromagnetic, with particles vibrating in a direction that is perpendicular to that of the wave, forming crests and troughs. the wave is mechanical, with particles vibrating in a direction that is perpendicular to that of the wave, forming compressions and rarefactions.

The wave is mechanical, with particles vibrating in a direction that is perpendicular to that of the wave, forming compressions and rarefactions.

Explanation:

Here the wave is propagating in the pavements and girders of a suspension which is of a rigid shape and size.

Here we can say that shape and size will always remain the same and there is no change in it, so here the wave will propagate in the medium in such a wave that it can not change the shape and hence it will not form crest and trough but it will propagate in such a wave that the medium particles will oscillates perpendicular to wave propagation and they will form compression and rarefaction in the medium at different positions

All the points where particles come closer will form compression and all points where particles move away are termed as rarefaction.

so here correct answer will be

The wave is mechanical, with particles vibrating in a direction that is perpendicular to that of the wave, forming compressions and rarefactions.

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.
