does wavelength affect speed of a sound
f6e0c5266f48ba75aed494d269fb2b75
Speed of sound The wavelength of any sound wave will be proportional to its speed and inversely proportional to its frequency. l = c / f, where l is the wavelength, c is the speed, and f … is the frequency. In air, at sea level, 20 C and dry conditions, the speed of sound is about 340 m/s. A high frequency might be 15000 Hz, so the wavelength of that wave would be about 2.27 cm.

Wavelength Assuming a sinusoidal wave moving at a fixed wave speed, wavelength is inversely proportional to frequency of the wave: waves with higher frequencies have shorter wavelengths, and lower frequencies have longer wavelengths. Wavelength depends on the medium (for example, vacuum, air, or water) that a wave travels through.

Wavelength where v is called the phase speed (magnitude of the phase velocity) of the wave and f is the wave's frequency. In a dispersive medium, the phase speed itself depends upon the frequency of the wave, making the relationship between wavelength and frequency nonlinear. In the case of electromagnetic radiation—such as light—in free space, the phase speed is the speed of light, about 3×108 m/s. Thus the wavelength of a 100 MHz electromagnetic (radio) wave is about: 3×108 m/s divided by 108 Hz = 3 metres. The wavelength of visible light ranges from deep red, roughly 700 nm, to violet, roughly 400 nm (for other examples, see electromagnetic spectrum).

- The amplitude of a sound wave determines it's pitch frequency loudness wavelength. Answers.com says: The pitch or note of a sound that we experience is determined by its wavelength or its frequency. The shorter the wavelength, the higher the frequency becomes, and the higher the pitch that we hear. The amplitude of a sound wave is the same thing as loudness. The loudness or amplitude corresponds to how much the wave is compressed. The wavelength of a wave is independent of its amplitude [loudness] and inversely proportional to its frequency. ~~ JUST so im not using some1 else'z work with out letting u know.

Refraction of Sound Sound rays always turn toward the layer where the speed of sound is lower. The more rapid the change in the speed of sound, the more pronounced the refraction. Figure 1. (a) Paths of sound rays when temperature decreases with altitude, (b) paths of sound rays when temperature increases with altitude. The refraction of sound in the atmosphere is due to spatial variations in the air temperature, wind speed, and wind direction. The temperature usually decreases with altitude up to an altitude of 15–20 km.

Refraction of Sound Waves The speed of a sound wave in air depends on the temperature (c=331 + 0.6 T) where T is the temperature in oC. Often the change in the wave speed, and the resulting refraction, is due to a change in the local temperature of the air.

- Frequency is the inverse of this, the number of cycles in a second. The distance sound travels during one period is the wavelength. All this is related by the formulas: The upside down y is lambda, which stands for wavelength. P is period, f is frequency, and s is the speed of sound.

Introduction to Computer Music: Volume One The speed at which sound propagates (or travels from its source) is directly influenced by both the medium through which it travels and the factors affecting the medium, such as altitude, humidity and temperature for gases like air.

As the frequency of sound is increased, does the wavelength increase or decrease? Thus if you use sound sources of higher frequencies, the wavelengths will decrease. This is because v= speed of sound = frequency * wavelength As v remains the same, increasing frequency,should decrease the wavelength.hus if you use sound sources of higher frequencies, the wavelengths will decrease. This is because v= speed of sound = frequency * wavelength As v remains the same, increasing frequency,should decrease the wavelength.

Speed of sound Since temperature (and thus the speed of sound) decreases with increasing altitude up to 11 km, sound is refracted upward, away from listeners on the ground, creating an acoustic shadow at some distance from the source.

The Wave Equation So in a time of one period, the wave has moved a distance of one wavelength. Combining this information with the equation for speed (speed = distance/time), it can be said that the speed of a wave is also the wavelength/period. Since the period is the reciprocal of the frequency, the expression 1/f can be substituted into the above equation for period.

How does changing the wavelength affect the speed of a wave? The wavelength of waves travelling with the same speed would  decrease if the frequency of the waves increases. This is because,  speed of a wave is the product of the dista … nce of the wavelength  times the frequency of the wave.   The velocity of a wave is usually constant in a given medium.

- The speed of a wave is the rate at which vibrations move through the medium. Sound moves at a faster speed in water (1500 meters/sec) than in air (about 340 meters/sec) because the mechanical properties of water differ from air.

Sound The speed of sound depends on the medium that the waves pass through, and is a fundamental property of the material. The first significant effort towards the measure of the speed of sound was made by Newton.

The Expanding Universe The wavelength and the frequency of the sound waves from the police car is the same in all directions. Therefore, observers on any side of the police car would hear the exact same sound. Remember the wave equation, We know the speed of sound in air is 330m/s and the wavelength for the sound waves from the siren are 1m.

The Speed of a Wave Answer: C. The medium is the same for both of these waves (the same container of nitrogen gas). Thus, the speed of the wave will be the same. Alterations in a property of a wave (such as wavelength) will not affect the speed of the wave. Two different waves travel with the same speed when present in the same medium.

- So I think we perceive amplitude as loudness in sound and brightness in light. We perceive frequency (and wavelength?) in sound as pitch? For light, wavenlength (and frequency?) are perceived as color? Or just wavelength? Since speed of light or sound is determined by the medium, wavelength and frequency would give us the same information?

How are frequency pitch amplitude wavelength and loudness all related? The shorter the wavelength, the higher the frequency becomes, and the higher … the pitch that we hear. The amplitude of a sound wave is the same thing as loudness. The loudness or amplitude corresponds to how much the wave is compressed.

- The speed of sound is faster in solid materials and slower in liquids or gases. The velocity of a sound wave is affected by two properties of matter: the elastic properties and density. The relationship is described by the following equation. Where: Cij is the elastic properties and p is the density.

Waves and Sound As the frequency of a sound is increased, the wavelength decreases. For example, during a concert, you do not hear the high notes in a chord before you hear the low ones; the sounds of all instruments reach you at the same time.

The Speed of Sound The faster a sound wave travels, the more distance it will cover in the same period of time. If a sound wave were observed to travel a distance of 700 meters in 2 seconds, then the speed of the wave would be 350 m/s.
