Recommended: waves and water dynamics
What comes to mind when someone says the word wave? Maybe you picture yourself waving your hand to say hello, or a wave on the ocean. In physics, a wave can be defined as a a repeating and periodic disturbance that travels through a medium and transfers energy from one point to another. This disturbance, or variation, can move up, down, forward or back, just think of the waves in the ocean. The medium is the substance or material that carries the wave, for instance, with ocean waves the medium would be the water itself. Wave motion transfers energy from one point to another, often without permanently moving the particles of the medium. Waves are made up of oscillations (movements back and forth at a regular speed) or vibrations. All waves have an equilibrium position, which is when all the acting forces are canceled or balanced, just picture the surface of the water completely flat and smooth.
The crest of a wave is the point on the medium that exhibits the maximum amount of positive or upward displacement from the rest position, they are the uppermost points of the wave. The trough of a wave is the point on the wave that exhibits the maximum amount of negative or downward displacement from the rest position, it is the lowest position of the wave.
There are many different kinds of waves. Two kinds of waves are transverse waves and longitudinal waves. A transverse wave is a wave that has its disturbance perpendicular to its direction of propagation; the particles do not move along with the wave; they simply vibrate up and down about their individual equilibrium positions as the wave passes by. A good way to visualize a transverse wave is a string or a rope being moved up and down. The rope is moving, but it is not going anyw...

The purpose of this experiment was to determine whether if the sound is affected when it travels through different length pipes. The method used to do this experiment was created by using 5 different PVC pipes in the lengths of 10, 20, 30, 40, and 50 centimeters. Then, using a tuning fork, sound will be produced on one end of the PVC pipe and measured with a decimeter on the other end. This experiment was recorded using 5 trials for each independent level and the average decibels (dB) for each pipe length were recorded.

Electromagnetic waves are waves that can propagate even though there is no medium. A magnetic field that changes with time can generate an electric field that also changes with time, and an electric field that changes with time can also produce a magnetic field. If the process is continuous it will produce a magnetic field and electric field continuously. If these magnetic fields and electric fields simultaneously propagate (spread) in space in all directions then this is a symptom of the wave. Such a wave is called an electromagnetic wave because it consists of an electric field and a magnetic field that travels in space.
3b.The waves are very high because they have nothing close to them to make the waves slow down.
2. What is the difference between waves and swells? Waves occur where the wind is blowing. Swells are waves that have moved away from the wind generating area and frequently give warnings of an approaching storm.
Sound waves are measured in frequency which can be defined as the number of pressure waves passing a fixed point in a set time. “The velocity of sound in seawater is approximately 1500ms”(Wright et al., 1995, p. 71) Wavelength is the distance
“...Waves are a disturbances that propagate energy through a medium” (Staroscik). One example of waves in these types of submarines is for sonar. Sonar works by emitting periodic sound waves through the water. The waves bounce off objects in the water back to

In physics, music is essentially a form of energy and is transferred by a wave. There are two basic kinds of waves. The first is a transverse wave where the medium vibrates at a right angle up and down causing the wave to move to the right. A compressional wave (or longitudinal wave) moves to the right and left because the medium vibrates in the same direction. Sound waves take the form of compressional waves and are caused by vibrations. Sound waves are distinguished by their speed, pitch, loudness and quality (timbre) (Lapp, 2003).
Since I've settled down and become a family man, however, I have discovered a whole new world of sounds that give me more pleasure than music ever did. Something I never thought possible. I would like to describe for you the world of sound that I experience in a typical day.
What distinguishes sound waves from most other waves is that humans easily can perceive the frequency and amplitude of the wave. The frequency governs the pitch of the note produced, while the amplitude relates to the sound le...
