The speed of sound is 330.0 m/s and the wave length of a particular sound wave is 33.0 meters. Calculate the frequency of the sound wave.

A)11,000 Hz B)10.0 Hz C) 0.10 Hz D)9.1 x 10-5 Hz

Respuesta :

Carlquist
v: velocity of wave
f: frequency 
L: wavelenght

v = fL => f = v/L => f = (330)/(33) => L = 10Hz

Answer:

B). f = 10.0 Hz

Explanation:

As we know the relation between frequency, wavelength and speed is given as

[tex]v = f \lambda[/tex]

here we know that

[tex]v = 330 m/s[/tex]

[tex]\lambda = 33 m[/tex]

now in order to find the frequency of the sound we can use above relation as

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

plug in all values in it

[tex]f = \frac{330}{33}[/tex]

[tex]f = 10 Hz[/tex]
