Answer:
Option A
0.01372 m
Explanation:
The speed of sound is a product of the wavelength and frequency hence
Speed=Wavelength * Frequency
Making wavelength the subject then
[tex]Wavelength=\frac {speed}{frequency}[/tex]
Substituting 343 m/s for speed and 25 kHz= 25000 Hz for frequency we obtain
[tex]Wavelength=\frac {343}{25000}=0.01372 m[/tex]
