Conversation

Have you ever heard about photoemission in physics?

Yeah, I think it has to do with electrons being emitted from metals, right?

Exactly! It's fascinating how light can cause such reactions.

It really is! I love learning about how different phenomena work.

Root Explanation

Photoemission → It is formed from "photo-" (from Greek "phōs", meaning light) and "emission" (from Latin "emittere", meaning to send out). The word describes the process of sending out electrons or other particles as a result of exposure to light.

Memory Tip

Think of 'light' ('photo-') causing something to 'send out' ('emission') particles — that's what photoemission means.
