Question

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

Answer 1

v: velocity of wave
f: frequency
L: wavelenght

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

Answer 2

B). f = 10.0 Hz

Step-by-step 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 = (v)/(\lambda)`

plug in all values in it

`f = (330)/(33)`

`f = 10 Hz`
