Across
- 2. The point where light rays meet after being reflected or refracted.
- 5. A mirror that curves outward and spreads light, creating smaller images.
- 7. A straight line that shows the direction light travels.
- 10. A wave of energy that travels through space without needing a medium.
- 11. A lens that curves inward and spreads light rays apart.
- 13. The spreading of light into different colors when it passes through a material.
- 15. The restriction of light waves to vibrate in one direction.
- 16. A material that lets light pass through clearly so you can see through it.
- 17. A dark area where light is blocked by an object.
- 19. A material that lets some light pass through, but you cannot see clearly through it.
- 20. A lens that curves outward and brings light rays together.
Down
- 1. Reflection of light from a rough surface where light scatters in many directions.
- 3. A mirror that curves inward and can focus light to a point.
- 4. Reflection of light from a smooth surface where rays reflect in one direction, forming a clear image.
- 6. The full range of all types of electromagnetic radiation, from radio waves to gamma rays.
- 8. The bouncing of light off a surface
- 9. The bending of light when it passes from one material to another.
- 12. The bending or spreading of waves when they pass through an opening or around an object.
- 14. A tiny particle of light that carries energy.
- 18. A material that does not let light pass through at all.
