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
