The middle panel is white noise (like the sound of a waterfall). White noise has equal energy at all frequencies, so the spectrum is a horizontal line. The lower panel is the sine tone added to the noise. The spectrum of the sum is just the sum of the spectra of the two components. Notice that you can see the tone very easily in the spectrum, but it is completely obscured by the noise in the waveform.
