Luminous

Summary: Objects that give out light are luminous. Most objects that you look at are non-luminous. They do not emit light. You can see them because they reflect light into your eyes. Light spreads out, just like Sound. Tags: science student-book-7 physics Created: 2026-05-21 Last Updated: 2026-05-21
