Morphology

disperse = sparse (semi-transparent) = dis + sperse

The optical sense ('separate into spectral colors') is an extension of the general idea of separation/scattering (related to 'sparse'), but it is a specialized technical usage and the stem is not a standalone modern base.

Etymology

The word disperse comes from the Latin parts dis- ('apart') and spargere ('to scatter') and shares its root with sparse, which means 'thinly spread'. So to disperse light is to 'scatter apart' its colours, which is why a prism breaks white light into a rainbow.
