Now here in this class, we basically look at a waves produced by guitar strain, right? now, the guitar string is to have a linear mass density that's a rail equals 1 .3 times 10 to minus 4 kilogram per meter.

And it has a length which is air equals 0 .94 meter long, right? and the strength is tuned by just tension, t equals 8 .5 newton, right? so what the speed do the waves travel on the string? well, that speed is given by the square root of t over row, right? so you have the t, you have the rail, you can easily work at the speed of the waves.

Fundamental frequency are for the strain is obviously, you know, for the fundamental frequency, the wavelength of the wave is actually twice dead of the lens, right? so the frequency will be simply given by, and is simply given by 2 pi.

If you look at the frequency, not the angular frequency, let me just write it differently...
