Across
- 1. is a colored material that is used to change the color of other substance
- 5. light is light generated by using phosphors to convert ultraviolet radiation to visible light
- 7. materials only absorb and reflect light; no light passes through them
- 8. of refraction is a property of a material that indicates how much the speed of light in the material is reduced compared to the speed of light in a vacuum
- 9. materials light but also scatter it
- 10. light is generated by heating a piece of metal until it grows
Down
- 2. materials transmit light without scattering it, so you can see objects clearly through them
- 3. light can have more than one wavelight, can travel in more than one direction, and does not travel in a constant direction
- 4. is an image of a distant object produced by the refraction of light through the air layers of different densities.
- 6. light is light of only one wavelength that travels in one direction with a constant distance
