Question

the wave length of sound in air is 10 cm . it's frequency is​

Answer 1

Answer:

3430 Hz

Explanation:

Given :

Wavelength = 10 cm = 0.1 m

Procedure :

As we know, Velocity = Wavelength × Frequency

As velocity of sound in air = 343 m/s

Hence, frequency = $\frac{velocity}{wavelength}$ = $\frac{343}{0.1}$ = 3430 Hz
