It contains a sine wave fundamental, and all its odd harmonics . The amplitude of each harmonic is 1/n, so the amplitude of the fifth harmonic, for example, would be 1/5 the amplitude of the fundamental. … A perfect square wave would have no even harmonics.
Read moreWhat is the spectrum of a square wave?
Frequency spectrum of a signal is the range of frequencies contained by a signal . For example, a square wave is shown in Fig. 3.5A. It can be represented by a series of sine waves, S(t) = 4A/π sin(2πft) + 4A/3π sin(2π(3f)t) + 4A/5π sin(2π(5f)t + …)

A square wave behaves the exact same way as a sine wave, in that as its fundamental frequency increases, you will see more cycles in a given amount of time . Square waves theoretically have infinite bandwidth.23 Eyl 2014
