Light Vocab

5. Wave – A wave of energy made of electric and magnetic fields that can travel through space.
6. – A dark area formed when an object blocks light.
10. Lens – A lens that curves outward and focuses light to a point.
11. – A material that lets some light through but scatters it, so objects aren’t clearly seen.
13. Lens – A lens that curves inward and spreads light rays apart.
14. Ray – A straight line used to show the path that light travels.
16. – A material that does not let light pass through.
17. – The alignment of light waves so they vibrate in one direction.
18. – A material that lets light pass through clearly.
20. Point – The point where light rays meet or appear to meet after reflection or refraction.

1. Mirror – A mirror that curves outward and spreads light rays apart.
2. Reflection – Reflection of light from a smooth surface where rays bounce off in one clear direction (like a mirror).
3. Mirror – A mirror that curves inward and can focus light to a point.
4. – The spreading of light into different colors because different wavelengths bend differently.
7. – A tiny particle of light that carries energy.
8. – The bending and spreading of light waves around edges or openings.
9. – The bouncing of light off a surface.
12. Spectrum – The full range of all types of electromagnetic waves, from radio waves to gamma rays.
15. Reflection – Reflection of light from a rough surface where rays scatter in many directions.
19. – The bending of light as it passes from one material to another.
