Across
- 2. the range of EM waves from radio waves to gamma rays.
- 5. EM wave that is used in remote controls and heaters.
- 7. a wave type that does not require a medium to travel- can travel through empty space.
- 9. the transfer of light energy to an object.
- 11. a wave typ e that occurs on top of a liquid like water waves - combination of longitudinal and transverse waves.
- 13. a disturbance that transfers energy from one place to another.
- 14. a wave type that requires a medium to travel.
- 15. a location where there is noting, not even air - outer space.
- 16. EM wave that causes sunburns and has higher energy and frequency than visible light.
- 17. light bending as it passes between two different media causing the wave to change speeds and directions.
- 19. the distance between two wave crests.
Down
- 1. matter that allows light to pass through
- 3. a type of wave that the particles of the wave vibrate perpendicular to the energy movement.
- 4. a type of wave that the particles of the wave vibrate parallel to the energy movement.
- 6. the height of a wave.
- 8. matter through which the light can not pass through.
- 10. light bouncing off a surface that it does not go through.
- 11. the spreading of light waves in all directions.
- 12. matter that transmits light but that does not transmit an image.
- 18. the number of waves that pass in a given amount of time.
