Answer:

34000

Step-by-step explanation:

Given :

Velocity in air = 340 m / sec

Wave length = 1 cm = 0.01 m

We know :

Velocity = wavelength / Time period

Time period = wavelength / velocity

But 1 / Time period = Frequency

Frequency = velocity / wavelength

Putting value here we get :

Frequency = 340 / 0.01 Hz

Frequency = 34000 Hz.

Therefore Frequency is 34000 Hz.

Answer:

34000

Step-by-step explanation:

v=frequency.wavelength

frequency=v/wave l

f=340/0.01(convert cm to SI unit m)

f=34000
