The frequency spectrum, as the name implies, is the representation method of the “time domain” signal in the “frequency domain”, which is usually converted by the “Fourier transform”. Usually the amplitude is the y-axis and the frequency is the x-axis.

A spectrogram plots time in Y-axis and frequencies in X-axis. A spectrogram also conveys the signal strength using the colors – brighter the color the higher the energy of the signal. A spectrogram explains how the signal strength is distributed in every frequency found in the signal. did luffy eat the flare flare fruit
