Across
- 2. an upright image that is achieved where the rays seem to diverge
- 10. A type of wave in which the medium's vibration is parallel to the direction of the wave
- 11. the bending of light rays as they pass from one medium to another, thereby changing the path of the rays
- 13. the change in the frequency of a wave in relation to an observer who is moving relative to the source of the wave
- 14. the slight bending of light as it passes around the edge of an object
- 15. If the crests of one of the waves coincide with the crests of the other, the amplitudes are additive
- 16. Waves that are created as a result of vibrations between an electric field and a magnetic field
- 18. A wave that oscillates perpendicularly to the direction of the wave's advance
- 19. occurs where rays converge
- 20. A substance that makes possible the transfer of energy from one location to another, especially through waves
Down
- 1. If the crests of one wave coincide with the troughs of the other wave, the resulting amplitude is decreased or may even be completely canceled
- 3. A measurement of the amount of energy transferred by a wave
- 4. When a ray of light approaches a smooth polished surface and the light ray bounces back
- 5. formed when two waves of the same frequency travel in opposite directions
- 6. When two light waves from different coherent sources meet together, then the distribution of energy due to one wave is disturbed by the other
- 7. The distance between identical points on successive waves
- 8. The highest part of the wave
- 9. A vibration in matter that transfers energy through a material
- 12. The time it takes to complete one cycle
- 17. The number of waves that pass a point in a certain period of time
- 18. The lowest part of the wave
