A sound wave with a wavelength of 2.5 m travels 660 m in 2 s. Calculate the frequency of the wave. (To calculate the speed of sound, remember: speed = distance/time.)

Answer:

[tex]f = 132\,hz[/tex]

Explanation:

The speed of the sound wave is:

[tex]v = \frac{660\,m }{2\,s}[/tex]

[tex]v = 330\,\frac{m}{s}[/tex]

The frequency is:

[tex]f = \frac{v}{\lambda}[/tex]

[tex]f = \frac{330\,\frac{m}{s} }{2.5\,m}[/tex]

[tex]f = 132\,hz[/tex]
