Across
- 3. chemical raction that happens with in a living organsim that produces light energy
- 4. like fulorestent light just energy is realest over muc longer periods oftime
- 7. heat energy produced by movement
- 11. objects reflects or absorb light
- 12. energy released from the nucleus made up of photons and newtons
- 14. emitting light as a result of being heated
- 15. energy transfer that does not need matter
- 17. things that make their own energy
- 19. light bounces of the object
- 20. object transmits or reflects light rays
- 23. energy genterated by the movment of charged particles such aselerctrons thriugh conducters
- 24. light that occurs naturally
Down
- 1. object transmints all light rays
- 2. the study of the science of light
- 5. a chemical reaction realulting in visade light to be created
- 6. must be a direct conversion from elctrisity to light
- 8. light goes into the object as energy
- 9. kinetic energy formed through movment
- 10. things that just reflect light from luminous objects
- 13. energy created by a chemical reaction
- 16. electric light- uses ultraviolet light from mercory vapor to make a coating called phospher glow
- 18. light passes through the object
- 21. light that does not occur naturally
- 22. a form of energy that is sometimes visible
