A wave is a disturbance that moves energy from one place to another. Only energy — not matter — is transferred as a wave moves. The substance that a wave moves through is called the medium.
Light, sound, and waves in the ocean are common examples of waves. Sound and water waves are mechanical waves; meaning, they require a medium to travel through.
Waves are essentially the movement of water molecules within the ocean, and are restricted to the surface layers of our oceans and seas. They involve the circular orbit of water molecules and are the agents of coastal change. Waves vary enormously in size and character, from ocean to ocean.
Mechanical waves are caused by a disturbance or vibration in matter, whether solid, gas, liquid, or plasma. Matter that waves are traveling through is called a medium. Water waves are formed by vibrations in a liquid and sound waves are formed by vibrations in a gas (air).

A wave is defined as "a periodic disturbance that moves through space." The disturbance could mean the high and low parts of an ocean wave, or the high and low pressure parts of a sound wave, etc. Periodic means that the disturbance repeats. As an example, consider a graph of y = sin(x). This is a wave.
wavelength, distance between corresponding points of two consecutive waves.
Description: Wavelength is the distance from one crest to another, or from one trough to another, of a wave (which may be an electromagnetic wave, a sound wave, or any other wave). Crest is the highest point of the wave whereas the trough is the lowest.
Wavelength the distance between any given point and the same point in the next wave cycle.
In physics, the term frequency refers to the number of waves that pass a fixed point in unit time. It also describes the number of cycles or vibrations undergone during one unit of time by a body in periodic motion.
Wavelength: The distance between 2 consecutive crest or troughs is called Wavelength. It is represented by the symbol λ(lamda).
amplitude, in physics, the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. It is equal to one-half the length of the vibration path.
Wave cycles: one completion of a wave's repeating up-and-down pattern. Frequency: the number of times the wave cycle repeats in a given time period. Velocity : speed of the wavelengths is measured in meters per second.
The highest surface part of a wave is called the crest, and the lowest part is the trough. The vertical distance between the crest and the trough is the wave height.
In the case of a wave, the speed is the distance traveled by a given point on the wave (such as a crest) in a given interval of time. In equation form, If the crest of an ocean wave moves a distance of 20 meters in 10 seconds, then the speed of the ocean wave is 2.0 m/s.
The frequency of a wave refers to how often the particles of the medium vibrate when a wave passes through the medium. Frequency is a part of our common, everyday language.
A wave carries energy from a source to a point some distance away. A wave is reflected by a barrier. The reflected wave moves away from the barrier at an angle that is equal to the angle with which the incoming wave moved towards the barrier. When a wave is slowed down, it refracts—that is, changes direction.
Waves that occur in water which is deeper than one-half their wavelength are not affected by the ocean bottom. They are called deep-water waves. 2. Deep-water waves do not interact with the ocean bottom because the orbital motions of deep-water waves do not extend to depths greater than one-half their wavelength.
Waves are most commonly caused by wind. Wind-driven waves, or surface waves, are created by the friction between wind and surface water. As wind blows across the surface of the ocean or a lake, the continual disturbance creates a wave crest.
They steep in gently. And when they break they brake gently and the top of the waves just spill downMoreThey steep in gently. And when they break they brake gently and the top of the waves just spill down the front of the wave. That's what we call it a spilling wave.
A sound wave is the pattern of disturbance caused by the movement of energy traveling through a medium (such as air, water, or any other liquid or solid matter) as it propagates away from the source of the sound. The source is some object that causes a vibration, such as a ringing telephone, or a person's vocal chords.
