I was reading about light waves and came across the term dispersive materials.

Oh really? What does that mean exactly?

Root Explanation

Dispersive → It is formed from "dis-" (meaning apart) and "spargere" (meaning to scatter). The word "dispersive" describes something that causes scattering or spreading apart.

Memory Tip

Think of something that makes things spread 'apart' ('dis-') and 'scatter' ('spargere') — that's what dispersive means.
