Across
- 2. falling beam of light on a surface
- 4. passing of light through matter
- 6. matter that transmits light but also scatter the light as it passes through
- 9. matter that does not transmit any light
- 11. red, green, blue
- 14. light beam reflect off all the points of the surface at the same angle
- 17. The idea that liht can act aseither particle or waves
- 18. release of light energy by particles of matter that have absorbed energy
- 20. “beyond violet” and have shorter wavelengths and higher frequencies than visible light
- 21. two primary colors are mixed
- 22. “below red” and emitted by the sun
- 23. narrow range of wavelengths that humans can see
- 24. waves combine and have a greater amplitude than individual waves had
- 25. Wave that can travel through space or matter-sonsirs of changing electric and magnetic fields
- 27. two or more waves overlap
- 28. shorter wavelengths and higher frequencies than radio waves
Down
- 1. bending of waves and barriers or openings
- 3. material that give a substance it’s color by absorbing some colors of light and reflecting others
- 5. the emission of energy in the form of EM waves
- 7. occurs when a wave bounces off an object
- 8. waves combine and have a smaller amplitude than individual waves had
- 10. matter through which visible light is easily transmitted
- 12. cover the wide range of waves in the EM spectrum
- 13. light beam reflect in many different angles
- 15. states ankle or incidence is equal to the angle of reflection
- 16. pigments yellow, cyan, magenta
- 19. the entire range of EM waves
- 26. bending of waves as it passes ar an angle from one medium to another
