If two sinusoidal waves having the same amplitude and wavelength travel in opposite directions along a stretched string, they can interfere to produce a standing wave. Unlike a traveling wave, a standing wave does not transfer energy from one end to the other.
For “certain frequencies” the interference of waves produces a standing wave pattern or you could say an oscillation pattern with nodes and anti nodes like this. And When this happens, we say that a standing wave has been created and the chord or string is said to be resonating at these certain frequencies, that are called resonant frequencies.
Well, physicists call this oscillation mode with the lowest frequency as the fundamental mode or the first harmonic when n=1. Then the second harmonic is the oscillation mode with n = 2, the third harmonic is with n= 3, and so on and so forth. Also, the associated frequencies are called f1, f2, f3, and so on and a collection of all possible oscillation modes is labeled the harmonic series, and n is called the harmonic number of the nth harmonic.

Thanks CS! That is a coll name you've given yourself! Whats the origin?
I would love to have an intelligent conversation with you about some of the resonant frequencies that I have found in my past research. I found it extremely intriguing how you did the math equations.. the way you did your physics almost scrambled my brain... And I'm not trying to say that as to mean disrespect or any such matter. I have complete respect for you and the knowledge that you bring to the table is a beautiful contribution to science as well as the world in my opinion. I will be subscribing and watching some more videos but for now on I am going to keep my notebook close as to keep track of the way I have been creating resident frequencies in standing waves using multiple vortex based mathematics specific numbers. I had died quite a few times and gained all knowledge from source and then began to teach myself a lot of these physics but only in a different way or maybe just a different way of doing the equations for my LRC circuits and resonating frequencies and such and would love to compare notes of reactive inductance and reactive capacitance capabilities along with an invention I believe with all my heart I came up with before anyone else (not speaking in an egotistical way) but now I'm not certain as of these days many technologies exist because of these standing waves and creating an implosion/explosion resonant frequency just in traffic inside of another standing wave with a larger amplitude therefore harnessing unlimited power and also inducing other resonant frequencies into the field around the { H3⅓ AND H5⅗ } to create all matter or substances organic or metallic and being real technology in this day and age is infatuating or lustful to say the least. Hope to speak to you soon just curious about some of my equations and how they work. My email address is ENERGYBUIES@GMAIL.COM 💜💜💜HAVE A BLESSED DAY💜💜💜

Can you explain where the extra length of string comes from when the standing wave is at its highest amplitude vs when it is a straight line.

Mark, it is the stretch in the string that elongates it

But sir wht is the difference between resonance and harmonics?

Let us take a guitar string to understand this. If one of the strings is plucked it will vibrate and we say that this is the natural frequency... and when it vibrates, a standing wave is produced. Then this natural frequency is also called a harmonic. We can force this guitar to vibrate at this harmonic or a standing wave pattern by connecting it with another object that kind of pushes it to vibrate at its natural frequency. So this is what we call resonance or when an object (guitar string here) is forced into vibrating at its natural frequency when another object vibrating at the same frequency is connected with it
Osm explanation... Got the concept 🙏
