Conversation

I was reading about light and its reflectivity the other day.

Oh, really? That sounds interesting!

Yeah, it’s amazing how some surfaces reflect light better than others.

Absolutely! It really affects how we see colors and brightness.

Root Explanation

Reflectivity → It is formed from "re-" (meaning back) and "flectere" (meaning to bend). The word describes the quality of bending light or other waves back from a surface.

Memory Tip

Think of light being 'bent back' ('re-') from a surface ('flectere') — that's what reflectivity means.
