Tides and waves are both caused by the gravitational pull of the moon and sun on Earth's oceans. Tides are long-period waves that move steadily across the ocean surface, while waves are shorter-period oscillations that move through the water in a more localized manner. Both tides and waves are influenced by the forces of gravity and serve important roles in shaping coastal areas and ecosystems.

In measuring air waves, equipment like microphones, sound level meters, and oscilloscopes are used. For water waves, devices such as wave gauges, buoys, and tide gauges are commonly employed to measure characteristics like wave height, period, and frequency.
The highest point in an ocean wave is called the crest. It is the peak of the wave where the water is at its highest elevation.
A transverse wave is one where the oscillations are perpendicular to the direction of wave propagation, like a wave on a string. A compression wave, or longitudinal wave, is where the oscillations are parallel to the direction of wave propagation, like sound waves in air.
A longitudinal wave is a wave where the particles of the medium move parallel to the direction of the wave propagation, like compressions and rarefactions in a spring. A transverse wave is a wave where the particles of the medium move perpendicularly to the direction of wave propagation, like the motion of a string being plucked.
Tidal waves are longitudinal waves. They move in the direction of the wave energy transfer, which in this case is the direction of the tide's gravitational pull.
