Across
- 1. the foundational colors of light that, when combined in various intensities, create all colors of the visible spectrum, culminating in white light when mixed equally
- 4. angle of reflection is the same angle of incidence
- 8. light refracts through the lens onto a light-sensitive area at the back of the eye
- 10. certain chemicals give off visible light after absorbing radiation which is not normally visible
- 11. the bending of light when it travels from one medium to another
- 13. the high part of a wave
- 17. light spreading out from a source in all different directions
- 18. a mirror that bulges in
- 19. the low part of a wave between a crest
- 20. the process where light strikes a surface and bounces back off the surface
- 22. the way of thinking about light as rays
- 23. light that results from light being released in chemical reactions
- 24. where chemical reactions occur inside of organisms to provide light
- 25. is a form of energy that you can see
Down
- 2. the emission of visible light by a hot object
- 3. when a cone has trouble seeing a color
- 5. any light that bounces off of that surface, if a reflected ray
- 6. in the vision process of changing the shape of the lens to adjust for different distances from an object being viewed
- 7. a theoretical or mathematical framework that describes how energy propagates through a medium through oscillations.
- 9. the ray of light that comes from the light source and hits a surface
- 12. a mirror that bulges out
- 14. the persistent emission of light following exposure to and removal of the source of radiant energy
- 15. a band of colors, as seen in a rainbow, produced by the separation of the components of light by their different degrees of refraction according to wavelength.
- 16. the nerve that connects the eye to the brain
- 21. the new direction of light after going through something
