General properties of waves — practice question
Fig. 5.1 shows a seismic wave generated by an earthquake. The diagram includes the compression and rarefaction regions labelled J and K.
(a)[2]
Describe how a longitudinal wave is different from a transverse wave.
(b(i))[1]
State whether this seismic wave is a P-wave (primary) or an S-wave (secondary). Give a reason for your choice.
(b(ii))[2]
Calculate the actual gap between point J and point K.
(b(iii))[3]
Calculate the time taken for the wave to pass. Show your working.
