Across
- 2. when parallel rays of light hit a smooth surface
- 6. a measure of how much a ray of light bends when it enters a new material
- 8. the bending of light rays resulting from the change in speed of the light that travels through more than one medium
- 11. the idea that the angle of light reflection equals the angle of incidence
- 12. a material that reflects or absorbs all of the light that strikes it
- 13. A relative expression of the intensity of the energy output of a visible light source
- 14. a material that scatters light as the light passes through
Down
- 1. when light rays are scattered by reflecting off of a bumpy surface
- 3. lenses that bend light toward a central focal point
- 4. the part of the electromagnetic spectrum, between infrared and ultraviolet, that can be sensed with the human eye.
- 5. a material that transmits light
- 7. lenses that bend light outward away from a focal point
- 9. when light does not pass through or reflect from material, but remains in the material as energy
- 10. colors that when combined in equal amounts produce white light
