Across
- 2. motion in which all points on a wave oscillate along paths at right angles to the direction of the wave's advance
- 7. the lowest part of the wave
- 9. a region in a longitudinal wave where the particles are closest together
- 12. distance between the resting position and the maximum displacement of the wave
Down
- 1. The highest surface part of a wave
- 3. a form of renewable energy that can be harnessed from the motion of the waves
- 4. a decrease in the density of something
- 5. waves where the displacement of the medium is in the same direction as the direction of the travelling wave
- 6. the distance between identical points
- 8. the number of waves that pass a fixed point in unit time
- 10. the substance that transfers the energy, or light from one substance to another substance or from one place to another, or from one surface to another
- 11. the time rate at which an object is moving along a path
