Across
- 1. parts of light that are reflected from an object
- 3. difference in electrical potential energy between two places in a circuit
- 7. lights moves through an object and bends
- 8. an electric circuit with a single path
- 12. the rate at which energy is transformed from one form to another
- 13. range of colors in light
- 14. thinner in the middle than at the edges
- 15. barely can see through an object
Down
- 2. build up of electrical charges on an object
- 4. motion of charged particles and the energy derived from that motion
- 5. a material through which electrical charges can easily flow
- 6. energy that we can see
- 9. shows the color of white light
- 10. an electric circuit with multiple paths
- 11. material tht does not allow the free movement of electircal charges
