Across
- 2. The returning of a wave to the medium from which it came when it hits a barrier.
- 4. A wave in which the medium vibrates in a direction perpendicular (transverse) to the direction in which the wave travels.
- 5. Description of materials that allow light to pass through them in straight lines.
- 7. A disturbance that travels from one place to another transporting energy, but not necessarily matter, along with it.
- 8. The bending of waves due to a change in wave speed.
- 9. A wave in which the medium vibrates in a direction parallel (longitudinal) to the direction in which the wave travels.
- 10. For a wave or a vibration, the maximum displacement on either side of the equilibrium (midpoint) position.
Down
- 1. The distance from the top of one crest to the top of the next crest or, equivalently, the distance between successive identical parts of the wave
- 3. The continuous range of electromagnetic waves that extends in frequency from radio waves to gamma rays.
- 6. Any bending of light by means other than reflection and refraction.
