It shows that a square wave is composed of a sinewave at the fundamental frequency of the square wave, plus additional sinewaves at the odd harmonic frequencies. The magnitude of the harmonic components is inversely proportional to the harmonic order. The more odd harmonics added, the faster the rising/falling edges are. These concepts are shown graphically as well as practically on an oscilloscope and spectrum analyzer.
