Answer:
The velocity of the sound wave is 540 meters per second.
Explanation:
The sound is a consequence of mechanic waves, the velocity of a mechanic wave ([tex]v[/tex]), in meters per second, is determined by following formula:
[tex]v = \lambda\cdot f[/tex] (1)
Where:
[tex]\lambda[/tex] - Wavelength, in meters.
[tex]\lambda[/tex] - Frequency, in hertz.
If we know that [tex]f = 2700\,hz[/tex] and [tex]\lambda = 0.20\,m[/tex], then the velocity of the sound wave is:
[tex]v = \lambda\cdot f[/tex]
[tex]v = 540\,\frac{m}{s}[/tex]
The velocity of the sound wave is 540 meters per second.
