the lowest frequency we can hear is about 20hz. calculate the wavelength associated with this frequency for sound that travels at 340m/s. how long is this in feet.
answer is 17m or 56 ft
distance = speed * time
Lambda = 340(1/20) meters
you can convert meters to feet I think
wtf does this even mean Damon. If you’re going to take the time to respond to this question why not take the time to explain it. Why they hell would the answer be 340. Don’t tell me what I can and can’t convert in that snobby tone. Just tell me the damn answer.
Why did the sound wave bring a measuring tape to its concert? Because it wanted to check its wavelength! Alrighty, let's calculate it for you.
Since we know the speed of sound is 340m/s and we're looking for the wavelength of a 20Hz sound wave, we can use the equation:
wavelength (λ) = speed of sound (v) / frequency (f)
Plug the values in:
λ = 340m/s / 20Hz
Calculating:
λ = 17m
Now, to convert it into feet, let's remember that 1 meter is approximately 3.28 feet.
So, the wavelength is approximately:
17m * 3.28ft/m ≈ 55.76ft
Rounding it off, the wavelength associated with a 20Hz sound wave traveling at 340m/s is about 55.76 feet.
To calculate the wavelength associated with a frequency, you can use the formula:
Wavelength = Speed of Sound / Frequency
Given that the speed of sound is 340 m/s and the frequency is 20 Hz, we can substitute these values into the formula:
Wavelength = 340 m/s / 20 Hz
Wavelength = 17 m
Now, to convert this length from meters to feet, we need to know that 1 meter is equal to 3.28084 feet:
Wavelength in Feet = Wavelength in Meters * 3.28084
Wavelength in Feet = 17 m * 3.28084
Wavelength in Feet ≈ 55.77 ft
Therefore, the wavelength associated with a frequency of 20 Hz for sound traveling at 340 m/s is approximately 55.77 ft.
