Across
- 4. motion in which all points on a wave oscillate along paths at right angles to the direction of the wave's advance
- 6. A wave in which the particles of the medium move in the same direction as the wave itself is moving
- 8. matter such as a liquid, gas or solid,that mechanical waves carry energy through
- 11. occurs when waves come together so that they completely cancel each other out
- 13. number of cycles per second in Hz
- 14. an increase or decrease in the frequency of sound, light, or other waves as the source and observer move toward or away from each other.
- 15. n electric and magnetic disturbance traveling through space at the speed of light
Down
- 1. the range of all types of EM radiation.
- 2. when light bounces off an object
- 3. happens when two waves overlap in such a way that they combine to create a larger wave
- 5. the size or strength of a cycle
- 7. The distance between any point on a wave to an identical point on the next wave.
- 9. the distance a wave travels in a given amount of time
- 10. the change in direction of a wave passing from one medium to another caused by its change in speed
- 12. the spreading of waves around obstacles
