Hi everyone!
I was reading up on sound waves and I got to the point where this website was describing how instruments produce standing waves through the interference of different frequencies but then it started to talk about how the length of air columns can affect the wavelengths of the sound and therefore change the frequency and I've seen this through real life experiences but this website doesn't seem to provide a good explanation. All they say us that nodes and antinodes are added to the column and that affects the frequency but how does one add antinodes and nodes? From what I've interpreted through other things I've learned is that the wavelength would remain constant regardless of how long the air column is, right?
Thanks for all your help!
