Water waves are primarily transverse waves, meaning that the particles of the medium (water) move perpendicular to the direction of the wave. However, water waves also have a small component of longitudinal motion, where the particles move parallel to the direction of the wave. This combination of transverse and longitudinal motion is what allows water waves to carry energy and propagate through the medium. **

No, radio waves, including extremely low frequency (ELF) waves, do not travel faster than the speed of light. The speed of light in a vacuum is approximately 299,792 kilometers per second, and radio waves, including ELF waves, travel at the speed of light. This means that radio waves, including ELF waves, do not exceed the speed of light. **
