Relationship between wave speed and density

Speed of Sound - Sound | HowStuffWorks

relationship between wave speed and density

Describe the relationship between the speed of sound, its frequency, and its wavelength. Sound, like all waves, travels at a certain speed and has the properties of of the medium's rigidity (or compressibility in gases) and its density. What is the relation between pressure and density by which speed of sound does not The sound waves faster in solids than in liquid and faster in liquid than in. Describe what elasticity and density are and what relationship they have to the The velocity of a sound wave is affected by two properties of matter: the In general, the bond strength between particles is strongest in solid materials and is .

This helps transmit the energy in-turn to the neighboring sphere's springs bondsand so on. In a real material, the stiffness of the springs is known as the " elastic modulus ", and the mass corresponds to the material density. Given that all other things being equal ceteris paribussound will travel slower in spongy materialsand faster in stiffer ones.

Effects like dispersion and reflection can also be understood using this model. Similarly, sound travels about 1. At the same time, "compression-type" sound will travel faster in solids than in liquids, and faster in liquids than in gases, because the solids are more difficult to compress than liquids, while liquids in turn are more difficult to compress than gases.

Some textbooks mistakenly state that the speed of sound increases with density. This notion is illustrated by presenting data for three materials, such as air, water and steel, which also have vastly different compressibility, more which making up for the density differences. An illustrative example of the two effects is that sound travels only 4.

The reason is that the larger density of water, which works to slow sound in water relative to air, nearly makes up for the compressibility differences in the two media.

A practical example can be observed in Edinburgh when the "One o' Clock Gun" is fired at the eastern end of Edinburgh Castle. Standing at the base of the western end of the Castle Rock, the sound of the Gun can be heard through the rock, slightly before it arrives by the air route, partly delayed by the slightly longer route.

The human ear could easily distinguish between tone A and tone C because of the quality. Therefore, we can say that quality distinguishes tones of like pitch and loudness when sounded on different types of musical instruments. It also distinguishes the voices of different persons. What are the three basic characteristics of sound? What is the normal audible range of the human ear?

What is intensity as it pertains to sound?

Speed of sound - Wikipedia

What characteristic of sound enables a person to distinguish one musical instrument from another, if they are all playing the same note? On the other hand, if the crest of an ocean wave moves a distance of 25 meters in 10 seconds the same amount of timethen the speed of this ocean wave is 2.

The faster wave travels a greater distance in the same amount of time. Sometimes a wave encounters the end of a medium and the presence of a different medium. For example, a wave introduced by a person into one end of a slinky will travel through the slinky and eventually reach the end of the slinky and the presence of the hand of a second person.

One behavior that waves undergo at the end of a medium is reflection. The wave will reflect or bounce off the person's hand.

The Speed of a Wave

When a wave undergoes reflection, it remains within the medium and merely reverses its direction of travel. In the case of a slinky wave, the disturbance can be seen traveling back to the original end. A slinky wave that travels to the end of a slinky and back has doubled its distance.

That is, by reflecting back to the original location, the wave has traveled a distance that is equal to twice the length of the slinky. Reflection phenomena are commonly observed with sound waves.

When you let out a holler within a canyon, you often hear the echo of the holler.
