Question

sound Travels at the speed of 340 metre per second if its wave is 1.7 cm what is the frequency of the wave​

Answer 1

Answer:

velocity of sound = 339 m/s

wavelength = 1.5 cm = 0.015 m

frequency =?

We know that

speed = wavelength * frequency

340 m/s = 0.015 m * frequency

frequency = 340 m/s / 0.015 m = 22666.66 Hz

frequency = 22666.66 Hz.

since the frequency is more 2kHz  

so it is inaudible..
