Across
- 1. when an object is heated to such a high temperature that it emits light.
- 3. is the process in which light strikes a surface is the incident ray.
- 5. a new direction of light
- 6. is the persistent emission of light following exposure to and removal of a source of radiant energy.
- 7. The bending of light through layers of air with different temperatures
- 11. is the form of energy that you can see.
- 12. it is hard to see through
- 15. The rate at which the waves move up and down
- 16. you can see through it
- 18. you cant see through it
- 20. The height of the crest or the depth of the trough from the rest position
- 21. occurs in organisms, where chemical reactions inside an organism provide energy for light.
- 22. Occurs mostly on rough, dark, opaque surfaces
- 24. The distance from crest to crest or from trough to trough
- 25. its automatic ability to change focus
- 26. a shape that curves out.
- 27. the path light takes after bouncing off a surfaceLaw of Reflection:
- 28. light that radiates from given source
Down
- 2. light that results from a chemical reaction.
- 4. The high part of a wave
- 8. cable-like bundle of over a million nerve fibers connecting each eye's retina to the brain
- 9. the emission of light
- 10. is bending of light when it travels from one medium to another
- 13. the opposite of convex
- 14. light that is represented by a ray.
- 17. is the light sensitive in the back of your eye
- 19. The low part of a wave
- 23. a ray of light that travels towards an object and strikes it then reflects or absorbs.
