What is the wavelength of a sound wave traveling at 340 m/s through the air at a frequency of 440 Hz?

Sagot :

The wavelength of wave is 1.29m  if the speed of wave is 340meters/sec and the frequency of the wave is 440Hz.

Right when you let out a boisterous cry inside a chasm, you consistently hear the reverberation of the holler. The sound waves travel through the medium; for this current situation, the air and skirt off the gorge wall and return to the beginning of the sound (you). The outcome is that you hear the reverberation of your holler.

We know that when an electromagnetic wave is going through speed v passing in a medium, it contains specific speed and frequency which is given by the expression

c=ν × λ

where c is defined as the speed of light in vacuum,

ν is  defined as the frequency of the wave and

λ is defined as the  wavelength of the wave.

Now, we have frequency(ν) = 440Hz, and speed(c)=340m/sec

So, using the above formula, we get

340=440×λ

=>λ=440/340

=>λ=1.29m

Hence, wavelength of sound wave is 1.29m
