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

Verified Answer :

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

\(v = f \lambda\)

here we know that

\(v = 330 m/s\)

\(\lambda = 33 m\)

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

\(f = \frac{v}{\lambda}\)

plug in all values in it

\(f = \frac{330}{33}\)

\(f = 10 Hz\)
