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

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

$f = \frac{330}{33}$

$f = 10 Hz$
