Which is the best description of a sound wave when the pitch of the sound is very high? It has a low frequency .
What best describes a sound wave?
For a sound wave traveling through air, the vibrations of the particles are best described as longitudinal . ... 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.
What best describes the pitch of sound?
Pitch, in music, position of a single sound in the complete range of sound . Sounds are higher or lower in pitch according to the frequency of vibration of the sound waves producing them.
How do you describe the wavelength of a sound with low pitch?
The shorter the wavelength, the higher the frequency , and the higher the pitch, of the sound. In other words, short waves sound high; long waves sound low.
When a pitch is high what is true about the wavelength of the sound wave?
As the frequency (pitch) increases, the wavelength becomes shorter according to the universal wave equation ( v=fλ ). The speed of the wave will not change, as it is dependent only on the properties of the medium through which the wave is traveling (ex.
How do you describe pitch?
Pitch refers to the quality of sound that we identify as being relatively high or low . There are two types of pitch: definite pitch, which is created by regular sound wave oscillations, and indefinite pitch, created by irregular sound waves.
Which sound has a higher pitch?
A high pitch sound corresponds to a high frequency sound wave and a low pitch sound corresponds to a low frequency sound wave.
What is the sound of the waves called?
The movement of the water particle is called vibration. The water that sound travels through is called a medium. A medium can be anything – a liquid (such as water), a solid (such as the seafloor), or a gas (such as air). A sound wave is called a compressional or longitudinal wave .
Which are the main characteristics of sound wave?
There are five main characteristics of sound waves: wavelength, amplitude, frequency, time period, and velocity . The wavelength of a sound wave indicates the distance that wave travels before it repeats itself. The wavelength itself is a longitudinal wave that shows the compressions and rarefactions of the sound wave.
How then is sound classified as a wave?
A wave is generated by the vibration of the particles of the medium through which it passes. Sound features particles that travel from one medium to another and is transported parallel to the direction of the air. Hence, we can say that sound is a longitudinal wave .
How do you describe the wavelength of a sound with a high pitch?
High pitch means small wavelength, and the size of a musical instrument is directly related to the wavelengths of sound it produces . ... The relationship of the speed of sound, its frequency, and wavelength is the same as for all waves: v w = fλ, where v w is the speed of sound, f is its frequency, and λ is its wavelength.
Why is sound a wave?
Sound energy, or energy associated with the vibrations created by a vibrating source , requires a medium to travel, which makes sound energy a mechanical wave. Pressure Sound Waves – Because sound waves consist of compressions and rarefactions, their regions fluctuate between low and high-pressure patterns.
What is the formula of wavelength of sound?
Namely, if we know the frequency (which is the number of wave repetitions per second, often given in Hertz, or Hz) and the sound speed (which is the speed the wave travels in meters per sec), then we can find the wavelength using the equation wavelength=speed/frequency.
Does higher pitch mean louder sound?
Children will often mix up pitch and loudness believing that a higher pitched sound is a louder one . Higher pitched sounds produce waves which are closer together than for lower pitched sounds. ... A smaller triangle or cymbal will make a relatively higher pitch note.
What are the 7 properties of sound?
- 7 Characteristics Of Sound, and Why You Need To Know Them. 9 Comments. ...

What are the 4 properties of sound?
Since sound is a wave, it has all of the properties attributed to any wave, and these attributes are the four elements that define any and all sounds. They are the frequency, amplitude, wave form and duration , or in musical terms, pitch, dynamic, timbre (tone color), and duration.
