A sound wave of frequency 440 Hz is played by a musician. What is the

wavelength of this sound wave (the speed of sound is given as 343 m/s) ?

343/440

Explanation:

Recall that v=d/t

Now, this is the same thing.

Frequency is 1/T and wavelength is the distance travelled in one period.

So Vs=f*λ

(the greek letter is used as the symbol of wavelength; it's arbitrary)
