Question

Audible range of frequency is 20hz to 2khz.Find the range of wavelength corresponding to this frequency given velocity of sound is 340m/s

Answer 1

$velocity \: = wavelength \: \times frequency \\ \\ f = 20 \\ v = 340 \\ wavelength = \frac{340}{20} = 17m \\ \\ \\ f = 20k \\ wavelength = 0.017m$
