Wind is the primary energy source that generates waves in the ocean. As wind blows across the water's surface, it transfers its energy to the water, causing it to oscillate and form waves.

The crest is the highest point of a wave, where the water is displaced vertically upward from its equilibrium position.

The trough is the lowest point of a wave, where the water is displaced vertically downward from its equilibrium position.

The wavelength is the distance between two consecutive crests or troughs of a wave. It is a measure of the horizontal extent of a wave.

The amplitude is the vertical distance between the crest and the trough of a wave. It is a measure of the wave's strength or intensity.

Wave velocity is the speed at which a wave travels. It is determined by the properties of the medium through which the wave is propagating.

The relationship between wave velocity, wavelength, and frequency is given by the equation v = λf, where v is the wave velocity, λ is the wavelength, and f is the frequency.

Refraction is the process by which waves transfer energy from one medium to another. It occurs when a wave encounters a boundary between two media with different properties, causing the wave to change direction.

Reflection is the process by which waves bounce back from a surface. It occurs when a wave encounters a boundary between two media with different properties, causing the wave to change direction and return to the original medium.

Diffraction is the process by which waves spread out as they pass through an opening or around an obstacle. It occurs when a wave encounters an edge or a barrier that is comparable in size to the wavelength of the wave.

Interference is the process by which two or more waves combine to produce a new wave pattern. It occurs when two or more waves overlap in space and time, resulting in a superposition of their amplitudes.

Breaking is the term used to describe the phenomenon where a wave breaks and collapses. It occurs when a wave reaches shallow water and the bottom of the water body begins to interfere with the wave's motion.

A tsunami is a large, destructive wave caused by an underwater earthquake or landslide. It is characterized by its long wavelength and high energy, which can cause significant damage when it reaches the coastline.

A rogue wave is a large, unpredictable wave that can occur in the open ocean. It is characterized by its sudden appearance and extreme height, which can be several times larger than the surrounding waves.

A storm surge is a series of large waves generated by a storm. It is caused by the strong winds and low pressure associated with the storm, which push water towards the coastline.
