Yeah, I learned about it in my physics class.

It's interesting how it makes the reflected rays stay parallel, right?

Absolutely, it’s really useful for things like road signs!

Root Explanation

Retroreflection → It is formed from "retro-" (meaning backward) and "reflectere" (meaning to bend back). The word describes the phenomenon of light being reflected back to its source, hence bending light backward.

Memory Tip

Think of light being 'bent back' ('reflectere') towards its source, which is what retroreflection means.
