- waves include primary wave (P-wave) and secondary wave (S-wave) .
- Seismic waves include P wave, S wave, Rayleigh wave and Love wave, of which the fastest is P wave.
- The Elastic waves include P-wave and S-wave.
- In a ( ), the oscillations are perpendicular to the direction in which the wave travels. An example is a wave on a string. A: transverse wave B: longitudinal wave
- What kind of wave does ultrasound belong to and has certain radiation? A: Electromagnetic wave B: Mechanical wave C: Particle wave D: Light wave
