Physics demo showing how standing waves can be set up on a string that is vibrating from one side where the other side of the string is tied down. Once we know the fundamental frequency, we can see additional harmonics if we go up in multiples of that fundamental frequency. This in a really important idea particularly for music whether you are talking about a stringed instrument like a guitar or aerophones like a flute. #physics #scienceexperiments #harmonics #standingwaves #stemtok
