Have you ever used a refractometer before?

No, I haven't. What does it do?

It's a cool tool that measures the index of refraction of liquids.

Root Explanation

Refractometer is formed from "re-" (meaning again or back), "frangere" (meaning to break), and "metron" (meaning measure). The word describes an instrument that measures the degree to which light is broken or bent when it passes through a substance.

Memory Tip

Think of light being 'broken' or 'bent' ('frangere') as it passes through something, and 're-' means again, while 'metron' refers to measuring. This helps you remember that a refractometer measures how light is refracted.
