The frequency of the wave is 132 Hz
Explanation:
To calculate the speed of the wave, we can use the following formula:
[tex]v = \frac{d}{t}[/tex]
where
d is the distance travelled by the wave
t is the time elapsed
For the sound wave in this problem, we have:
d = 660 m is the distance travelled
t = 2 s is the time interval considered
Substituting and solving for v, we find the speed of the sound wave:
[tex]v=\frac{660}{2}=330 m/s[/tex]
Now we can calculate the frequency of the wave by using the wave equation:
[tex]v=f\lambda[/tex]
where
v = 330 m/s is the speed of the wave
[tex]\lambda=2.5 m[/tex] is the wavelength
f is the frequency
Solving for f, we find:
[tex]f=\frac{v}{\lambda}=\frac{330}{2.5}=132 Hz[/tex]
