Across
- 2. motion in which all points on a wave oscillate along paths at right angles to the direction of the wave's advance
- 3. is a vibration that propagates as an acoustic wave, through a transmission medium such as a gas, liquid or solid
- 5. involves a change in direction of waves when they bounce off a barrier.
- 9. the distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave.
- 10. combinations of high-frequency electrical fields and magnetic fields in the wavelength range from the infrared through the visible to the ultraviolet light
- 11. is the opposite of a crest, so the minimum or lowest point in a cycle.
- 12. the maximum amount of displacement of a particle on the medium from its rest position
- 13. a change in the direction of waves as they pass from one medium to another.
Down
- 1. allowing light, but not detailed shapes, to pass through; semitransparent.
- 4. a substance or material that can carry a wave.
- 6. is a point on a surface wave where the displacement of the medium is at a maximum
- 7. an electromagnetic wave which travels through the vacuum of outer space.
- 8. the waves where the displacement of the medium is in the same direction as the direction of the travel of the wave.
