Answer:
18,850 Hz
Explanation:
We need to figure out the wavelength of the sound wave.
Thus,
Wavelength = 1000 * Lowest Amplitude Wave
Wavelength = 1000 * 2.0 * 10^(-5)
Wavelength = 0.02
Or,
[tex]\lambda=0.02[/tex]
Now, we need the frequency of this wave. It goes by the formula:
[tex]f=\frac{v}{\lambda}[/tex]
Where
f is the frequency in Hz
v is the speed of sound in air (to be 377 m/s)
[tex]\lambda[/tex] is the wavelength (we found to be 0.02)
Substituting, we find the frequency:
[tex]f=\frac{v}{\lambda}\\f=\frac{377}{0.02}\\f=18850[/tex]
The wave has frequency of 18,850 Hz
