Transverse and longitudinal waves
Physics · Secondary 4 · Medium · Transverse and longitudinal waves
In an earthquake, S-waves (secondary waves) cause the ground to move side-to-side while the wave itself travels forward through the Earth. How are the ground vibrations related to the direction of S-wave travel?
- They are perpendicular to the direction of wave travel.
- They are parallel to the direction of wave travel.
- They are opposite to the direction of wave travel.
- They are in random directions with no pattern.
