The highest frequency humans can hear is about 20,000 hz. what is the wavelength of sound in room temperature air at this frequency? what is the wavelength of the lowest sounds we can hear, about 20 hz?

(a) Wavelength and frequency of a wave are related by the following equation:

where
is the wavelength
f is the frequency
v is the speed of the wave.

The speed of sound at room temperature is approximately , so we can find the wavelength corresponding to a frequency of  by using the previous relationship:


(b) the lowest sound we can hear has a frequency of f=20 Hz. Using the same relationship we used in the previous part of the exercise, we can find the corresponding wavelength:

Iwas going to ask that quesytion  sorry dude i dont  know : (    : /

Ithink it’s 98 because jajajjajansmsmjs
