sound waves
ocean waves
ultraviolet waves
earthquake P-waves
earthquake S-waves
radio waves

Answer 1

Sound waves.
Eathquake P-Waves

Answer 2

Sound waves and earthquake P-waves are longitudinal waves.

Step-by-step explanation:

Longitudinal waves are waves in which the displacement through the medium is in the same direction of movement of the wave, independent of the direction.

There are included in the concept of longitudinal wave: sound waves (vibrations in pressure, particle displacement and velocity of particles propagated in an elastic medium) and earthquake waves of type P (created by earthquakes and explosions).
