I was reading about reradiation and how it affects our environment.

Oh really? I didn't know that could have such an impact.

Yeah, it’s interesting how absorbed radiation can change form.

Definitely! It makes you think about energy in a whole new way.

Root Explanation

Reradiation → It is formed from "re-" (meaning again) and "radiation" (from Latin "radiatio", meaning a sending out or emitting). The word refers to the process of emitting energy again after it has been absorbed.

Memory Tip

Think of 'again' ('re-') and 'sending out' ('radiation') to remember that reradiation means to emit energy again.
