Across
- 2. the process when one thing becomes part of another thing
- 4. the number of waves that pass a fixed point in unit time
- 6. the distance from the center line to the top of a crest or to the bottom of a trough
- 7. Wave, a wave that is an oscillation of matter, and therefore transfers energy through a medium
- 8. the opposite of a crest
- 10. the process of light bending around an obstacle
- 11. Wave, a wave whose oscillations are perpendicular to the direction of the wave's advance
- 13. where the particle motion is in the same direction in which the wave is propagating
- 14. point on a wave is the maximum value of upward displacement within a cycle
- 15. Wave, A wave consisting of a periodic disturbance or vibration
Down
- 1. the passage of electromagnetic radiation through a medium
- 3. the substance that transfers the energy
- 5. the reduction of an item's density, the opposite of compression
- 9. the distance between identical points in the adjacent cycles
- 12. the change in direction of a wave passing from one medium to another
