If the wavelength of the sound wave is 1.3 meters, what is the frequency?
L = 1.3m * 3.3ft/m = 4.29ft.
L = V(1/F) = 4.29FT,
L = 990ft/us * (1/f)us = 4.29,
L = 990 / f = 4.29,
4.29f = 990,
f = 990 / 4.29 = 231Mh.
CORRECTION!
The speed of sound in air = 343m/s.
L = 343m/s * (1/f)s = 1.3m,
343 / f = 1.3,
1.3f = 343,
f = 343 / 1.3 = 263.8Hz.
To find the frequency of a sound wave, you can use the formula:
ν = c / λ
where:
ν is the frequency,
c is the speed of sound, which is approximately 343 m/s in air at room temperature,
and λ is the wavelength.
Substituting the given values:
ν = 343 m/s / 1.3 m
ν ≈ 263.84 Hz
Therefore, the frequency of the sound wave is approximately 263.84 Hz.
To find the frequency of a sound wave given the wavelength, you can use the equation:
frequency = wave speed / wavelength
However, in order to use this equation, we need to know the wave speed. The wave speed of sound depends on the medium through which it is traveling. In this case, let's assume we are dealing with sound waves traveling through air at room temperature.
In dry air at room temperature, the speed of sound is approximately 343 meters per second. Now we can substitute the values into the equation:
frequency = wave speed / wavelength
frequency = 343 m/s / 1.3 m
By performing the division, we find that the frequency is approximately 264 Hz.
