1. The problem statement, all variables and given/known data
What are the wavelengths in air of the lowest and highest audible frequencies if te range of human hearing is 20 Hz to 20 kHz and the sped of sound is 342 m/s?

2. Relevant equations
v= $$\lambda$$f

3. The attempt at a solution
v= $$\lambda$$f
342 = 20 Hz $$\lambda$$
$$\lambda$$ = 17.1

Am I supposed to also do 20 kHz? Would 20 kHz be equal to 20,000?

Yes, it would be equal to 20,000 Hz.
