Question

What are the wavelength limits of the audible range of the sound spectrum? (Use the speed of sound in air. The speed of sound in air is 344 m/s. The audible range of the sound spectrum contains frequencies as low as 30 Hz and as high as 25 kHz.)

Answer 1

c = frequency x wavelength
344 m/s = 25000 Hz x w
solve for wavelength in meters.

Do the same for 30 Hz

Answer 2

c= frequency * Wavelength
a) 344 m/s / 25000 = w
w= 0.01376 m
b) 344 m/s / 30 = w
w= 11.4667
