It's a wavelength graph. No sine or cosine functions, no triangles.

1. What is the frequency and wavelength of the sound wave that produced the graph? 2. How would you find the wavelength of the graph? 3. I used speed = wavelength x frequency, changed it into frequency = speed / wavelength, used 343 m/s as the speed. I'm just stuck on how to get...
