Human hearing is most sensitive around 2500 Hz. If the speed of sound is 340 m/s, what is the wavelength of this sound?
A) 0.14 m
B) 7.4 m
C) 340 m
D) 2160 m

Question

The formula for wavelength is: 
wavelength = speed of sound / frequency 
We are given the frequency of 2500 Hz and the speed of sound of 340 m/s. Plugging these values into the formula, we get: 
wavelength = 340 m/s / 2500 Hz 
wavelength = 0.136 m 
Therefore, the best choice is A) 0.14 m, which is the closest value to the calculated wavelength.
