How do you describe a sound wave?
Sound wave can be described by five characteristics: Wavelength, Amplitude, Time-Period, Frequency and Velocity or Speed. The minimum distance in which a sound wave repeats itself is called its wavelength.
What are the parts of a wave describe each?
Wave Crest: The highest part of a wave. Wave Trough: The lowest part of a wave. Wave Height: The vertical distance between the wave trough and the wave crest. Wave Length: The distance between two consecutive wave crests or between two consecutive wave troughs.
What are the 2 parts of a sound wave called?
frequency
What best describes a sound wave?
A sound wave can also be described as a longitudinal wave. In a longitudinal wave, a source vibrates back and forth, causing air molecules to move back and forth in the same (in other words, parallel) direction that the wave is transmitted. hendikeps2 and 7 more users found this answer helpful.

What is the sound of the waves called?
As StoneyB suggested, roar and crash of the surf are common descriptions. Some other terms often used include pounding surf, in sense “Causing heavy or loud throbs”, and rumble of surf, in sense “A low pitched irregular noise, such as that of thunder or a hungry stomach”.
Why is sound a wave?
Sound is produced when an object vibrates, creating a pressure wave. This pressure wave causes particles in the surrounding medium (air, water, or solid) to have vibrational motion. As the particles vibrate, they move nearby particles, transmitting the sound further through the medium.
Who discovered sound waves?
Da Vinci
How then is sound classified as a wave?
Sound waves in air (and any fluid medium) are longitudinal waves because particles of the medium through which the sound is transported vibrate parallel to the direction that the sound wave moves. These back and forth vibrations are imparted to adjacent neighbors by particle-to-particle interaction.
Does sound travel faster than light?
The speed of sound through air is about 340 meters per second. It’s faster through water, and it’s even faster through steel. Light will travel through a vacuum at 300 million meters per second. No information can propagate faster than the speed of light.
What materials can sound not travel through?
We know light can travel through a vacuum because sunlight has to race through the vacuum of space to reach us on Earth. Sound, however, cannot travel through a vacuum: it always has to have something to travel through (known as a medium), such as air, water, glass, or metal.
Why does sound travel slower in rubber?
Particles that return to their mean position quickly are ready to move again more quickly, and thus they can vibrate at higher speeds. Therefore, sound can travel faster through steel (which has high elastic properties) than it can through rubber (which has lower elastic properties).
What happens when sound is absorbed?
As sound travels through a medium such as water, it gets absorbed – caught by the molecules within the medium. The medium actually changes some of the acoustic energy of the sound wave into heat. One way that this happens is that the acoustic energy of the sound causes the molecules of the medium to start vibrating.
How is sound reflected and absorbed?
A hard material such as concrete is as dissimilar as can be to the air through which the sound moves; subsequently, most of the sound wave is reflected by the walls and little is absorbed. Reflection of sound waves off of surfaces can lead to one of two phenomena – an echo or a reverberation.
Does sound travel faster in steel or rubber?
Particles that return to their resting position quickly are ready to move again more quickly, and thus they can vibrate at higher speeds. Therefore, sound can travel faster through mediums with higher elastic properties (like steel) than it can through solids like rubber, which have lower elastic properties.
Is sound travel in water?
Thus sound waves travel much faster in water than they do in air. In freshwater at room temperature, for example, sound travels about 4.3 times faster than it does in air at the same temperature. Sound keeps its energy longer when traveling through water because the particles can carry the sound waves better.
How fast does sound travel in water?
about 1,480 meters per second
How the sound is travel?
Sound vibrations travel in a wave pattern, and we call these vibrations sound waves. Sound waves move by vibrating objects and these objects vibrate other surrounding objects, carrying the sound along. Sound can move through the air, water, or solids, as long as there are particles to bounce off of.
How does sound travel in a tube?
Sound waves are longitudinal waves in a medium such as air. The molecules in the medium vibrate back and forth from their equilibrium position. For example, when a musician blows into a tube such as a flute, the sound produced comes from waves that travel along the length of the tube.
How is sound measured?
We measure sound intensity (also referred to as sound power or sound pressure) in units called decibels. Using the logarithmic decibel scale, if a sound is 80 decibels, and we add another 10 decibels, the sound will be ten times more intense, and will seem about twice as loud to our ears.
Does sound travel in a straight line?
In the simplest situations, sound also travels in straight lines. In the ocean, however, interactions between the sound and water make the transmission of sound much more complicated. These effects include reflection, bending (refraction), and scattering.
Do sound and light waves travel in a straight line?
The chapter further discusses the transmission of light and sound. Light energy, transmitted from a source travels in a straight line and is reflected by a mirror, the angles made by the incident light and the reflected light being equal. Sound energy from a source travels in a straight line and is reflected by a wall.
Do sound waves travel in all directions?
Sound vibrations, then, travel outwards in all directions in waves from a sound source. It can be seen that while the wave of compressed molecules moves away from the source, the molecules themselves only move a very small distance to and fro.
Does light travel in straight lines?
Any physics student knows that light travels in a straight line. But now researchers have shown that light can also travel in a curve, without any external influence. Out in space, light rays passing near very massive objects such as stars are seen to travel in curves.
Why do light travel in a straight line?
Since the wavelength of light (4000 to 8000 ) is very small as compared with the size of ordinary object and apertures, diffraction of light is not easily noticeable and hence light appears to travel in a straight line.
