• 💡 Light travels in a straight line. We call these lines rays.
• 🔦 Light sources can be natural (like the sun) or artificial (like a lamp).
• ➡️ Light travels very fast! Approximately $300,000,000$ meters per second.
• 🌑 Opaque objects block light completely, creating shadows.
• 👓 Transparent objects allow light to pass through them.
• ✨ Translucent objects allow some light to pass through, but not all.
• 🌈 Reflection is when light bounces off a surface.
• refractioin is when light bends as it moves from one material into another.
