Question

a sound wave of wavelength 7cm travel in air with speed 350 m/s calculate the frequency​

Answer 1

hey dear

here is your ans.

ANSWER

Speed of the sound is,

v=vλ

v=

λ

v

=

0.01

340

=34000Hz

Our audible range is 20 Hz 20 kHz. The obtained frequency is above this value. Since the given sound wave belongs to the ultrasonic range, it is not audible.

please give 10 thanks in my answer....

Answer 2

Answer:

5000 hz

Explanation:

V = f × wavelength

where V is velocity,

f is frequency.

therefore.......

350= f × 0.07m

f = 5000 hz
