Morphology
The phrase combines 'visible' (able to be perceived by the eye) and 'spectrum' (a band of colors or wavelengths) in a fully compositional way, so it clearly denotes the band of light wavelengths that can be seen. This is a literal, cross-linguistically common scientific compound, so a B1 learner who knows both constituents should understand the meaning.
Etymology
Visible spectrum comes from the simple image of white light passing through a prism and fanning out into the colors of a rainbow. The word visible means 'able to be seen' and spectrum means a 'range of colors', so the phrase describes the range of light our eyes can see.
