LIGHT, COLORS AND REFLECTION
Across
- 5. objects which emit light on their own
- 6. number of different types of EM wave
- 13. a copy of the object formed by reflected or refracted rays of light
- 14. material that permits light to pass through
- 15. Any two colors that combine to form white light
- 17. objects that are capable of reflecting light to our eyes
- 18. two primary colors combine in equal amounts
- 19. result of the combination of blue and green light
- 20. color which has the shortest wavelength
- 22. result of the combination of blue and red light
Down
- 1. happens when light is scattered in different directions
- 2. occurs when a wave bounces back after striking a barrier
- 3. is transparent optical element with flat, polished surfaces that refract light with at least two non-parallel surfaces
- 4. Smooth, shiny surfaces have this type of reflection
- 5. angle of incidence is equal to angle of reflection
- 7. a material that transmits some light but also scatter light in all directions
- 8. result of the addition of blue, red and green light
- 9. material that allows no light to pass through
- 10. three colors that can combine to make any other color
- 11. the portion of the spectrum that our eyes sense
- 12. color which has the lowest frequency
- 16. bending of waves
- 18. are places where light is “blocked”
- 21. happens when yellow, cyan and magenta were combined
- 23. color formed when yellow and cyan are combined
