This paper presents an experimental technique to observe the vibration tracks of string standing waves. From the vibration tracks, we can analyse the vibration directions of harmonic waves. For the harmonic wave vibrations of strings, when the driving frequency f s = Nf n (N = 1, 2, 3, 4, . . . ), both resonance and non-resonance standing waves can simultaneously appear and produce a vibration superposition. These discussions are useful for teaching, understanding experiments and illustrating theory.
