Morphology
The meaning is directly compositional: 'electromagnetic' specifies the type of phenomena (electric and magnetic radiation) and 'spectrum' denotes a range or band, so together they denote the range of electromagnetic wavelengths/frequencies. This is a regular scientific noun–noun compound following common compositional patterns (and paralleled in many languages), so a B1 learner who knows both constituents should be able to infer the meaning.
Etymology
Electromagnetic spectrum comes from two simple images: electromagnetic because these waves come from electric and magnetic forces, and spectrum meaning a range like a rainbow. Scientists saw that light and other invisible waves form one long band from radio waves to X-rays, so the phrase means the full 'range' of these waves.
