In reality, the amplitude varies with distance traveled due to the loss of energy. However, phase/frequency of the sound waves do not change. It only depends on the source, nothing else.

Not quite loss of energy, but spreading of energy by area as each wave-front occupies an expanding spherical surface.
'
The attenuation therefore is according to the square of the distance. Double the distance and you quarter the amplitude; at four times distance the sound is one-sixteenth its source level. The energy is still there but spread more thinly. In deciBel terms the drop is 3dB per doubling of distance.

There are actual losses by conversion to heat, but these are more complex, such as absorbtion by the medium through which the sound is travelling.

In other words, their product is always the same number, and is called
the "speed" of the wave.

If the frequency of a sound wave is multiplied by ten what happens to the wave length?
it gets divided by 10; frequency = speed/wavelength; wavelength = speed/frequency
If a wave has a low frequency how do you describe the wave length?
The frequency of a wave is not directly related to the wave length. A low frequency wave or a high frequency wave may be either long-wave or short-wave.
How are wave speed frequency and wave length related to the wave amplitude?
Frequency is the amount of bumps there are in the wave. The higher the frequency the lower the wave length and vise versa. some equations are E=hv C=vw h=Plancks Constant(6.626x10 to the -34) C=3.0x10 to the power of 8
The pitch of a sound wave is its wavelength?
Kind of. The pitch of a sound wave is its frequency, and because frequency = 1 / wavelength its pitch is related to the wave length. So to answer, no, the pitch of sound is not the wavelength itself, rather it is the inverse of the wavelength ( 1/wavelength)falseACJM
How is a waves frequency related to a waves length?
The product of the wave's frequency and the wave's wave length is equal to the speed of propagation of the wave.
Sounds can vary in volume and what?
Sound waves can vary in amplitude (volume), fequency (pitch), and wave length. Wave length is a resulting factor of frequency as the speed is usually constant. approx 350m/s. Speed = wavelength x frequency (speed = distance / time, frequency = 1/time)
The high the frequency of a sound wave means?
the shorter the wave-length
What are characteristics of sound energy?
The main characteristics of sound are frequency, amplitude and wave length
If the frequency of a sound wave is multiplied by ten what happens to the wave length?
it gets divided by 10; frequency = speed/wavelength; wavelength = speed/frequency
If a sound gets louder does the wavelength of the sound it produces increase?
No. The length of a sound wave is it's frequency. Volume will increase the wave's AMPLITUDE.
How does the frequency and wave length of the sound waves be produce and changed with a guitar?
because it makes sound
What are some characteristic of sound energy?
The main characteristics of sound are frequency, amplitude and wave length
Is wave a long a sound?
There is no set length on any sound wave. Sound waves vary hugely in thelength that they can be.The length of any sound wave is (the speed of sound in the current medium)/(the frequency of the sound) In air at sea level, the wavelengths in the audible range of frequencies rangefrom 1.72 centimeters (at 20 KHz) to 17.2 meters (at 20 Hz) ... a ratio of 1,000.
What is a radio wave's relative wavelength and frequency is?
The wave length and frequency of course vary, the frequency ranges from 3kHz to 300 GHz. The wavelengths are longer than infrared.
What increases when sound wave travel in solid from gas medium frequency or wavelength?
Velocity increases when sound waves travel from gas medium to solid medium. As velocity = frequency * wave length and the frequency does not change, v is directly proportional to the wave length... Hence the wavelength increases.
What is the equation used to find the speed of sound?
Speed = Frequency * Wave length.
If a wave has a low frequency how do you describe the wave length?
The frequency of a wave is not directly related to the wave length. A low frequency wave or a high frequency wave may be either long-wave or short-wave.
