Question

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.

Answer 1

Answer:

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.

Answer 2

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

A suspension bridge is a kind of bridge that is supported by girders in order for it to become stabilized and have a maintained shape. Now, when there is no mechanical energy happening on each ends of the bridge, the tendency is for it to collapse. That’s why the mechanical energy that is found in between the bridge is the one causing it to become compressed and sturdy in its position.
