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 anywhere, and it moves up and down.
A longitudinal wave has its disturbance along the direction of propagation. The particles do not move up or down with the wave; they simply oscillate back and forth about their individual equilibrium positions. The wave itself is the motion of the compressed region. Think of a longitudinal wave as a slinky. The slinky also moves without actually going anywhere, but it goes back and forth rather than up and down.
A compression is the point on the medium through which a longitudinal wave is traveling that has the maximum density. Think of the tight areas of the slinky as the compressions that move through the wave. A rarefaction is a point on a medium through which a longitudinal wave is traveling that has the minimum density, those would be the stretched out parts of the slinky.
While a transverse wave has an alternating pattern of crests and troughs (tops and bottoms) and it vibrates up and down, a longitudinal wave has an alternating pattern of compressions and rarefactions (dense and less dense areas) and vibrates back and forth.
There are several properties that can be found in a wave. One of them is amplitude, which is the maximum displacement of wave in relationship to the...

Instead of having sound waves that move up and down, these sound waves move back and forth. (Kessler) In spite of their differences, both of these waves have amplitude and frequency which in turn have their own separate effects on the properties of sound. Amplitude determines the intensity, in other

Harmonics and resonance A guitar string will naturally vibrate at certain frequencies; these frequencies are known as harmonics. The natural frequency at which an object vibrates at depends upon the tension of the string, such as the tension and the linear density of

1015 words - 4 pages comprises of one single frequency, which in fact is the simplest oscillation that can occur in nature. This means, that it cannot be further analyzed in simpler oscillations. The complex sound, on the other hand, consists of a fundamental frequency (which is the lowest one and usually carries most of the intensity) and of some other called overtones. When these overtones are integer multiples of the fundamental (including the fundamental), then we talk

Low frequencies often carry farther than high frequencies because of attenuation, or atmospheric absorption. This results from the fact that sound is a pressure wave of vibrating molecules.

Physics of sound

838 words - 3 pages backward it is called rarefractions. Sound requires a medium to travel; therefore, it cannot travel in space, which is a vacuum with no medium. The number of compressions and rarefractions per second is called frequency, The more rapidly and object vibrates, the higher the frequency. Frequency is measured in hertz. As the frequency of a sound wave increases, the wavelength decreases. Wavelength is the distance between one point on a wave to the

The frequency of a wave refers to how much the particles of the medium vibrate when a wave passes through a medium. Another important factor would be resoundingly; resonance comes from Latin and means “resound”, or to sound out together with a loud sound. Resonance is a common cause in the sound production of

Amplitude modulation is the oldest method of transmitting voice and music through the airwaves is by amplitude modulation. This is accomplished by combining a sound wave from a

Sound: More Than What You Hear

4387 words - 18 pages . As the vibrating object then moves inward, the medium fills in the space formerly occupied by the object. The resulting region, called a rarefaction, is less dense than normal. As the object continues to move outward and inward, a succession of condensations and rarefactions travels away from the object.Scientists describe sound in terms of (1) frequency and pitch, (2) wavelength, (3) intensity and loudness, and (4) quality.Frequency and pitch
