Across
- 3. Description of materials that allow light to pass through them in straight lines.
- 6. In the context of physics, the time required for vibration or a wave to make one complete cycle. In chemistry, a horizontal row in the periodic table.
- 8. For a wave or a vibration, the maximum displacement on either side of the equilibrium (midpoint) position.
- 9. An energy-carrying wave produced by an oscillating electric charge.
- 10. 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.
Down
- 1. A wave in which the medium vibrates in a direction parallel (longitudinal) to the direction in which the wave travels.
- 2. A wave in which the medium vibrates in a direction perpendicular (transverse) to the direction in which the wave travels.
- 4. The combined effect of two or more waves overlapping.
- 5. The change in frequency of a wave due to the motion of the source (or due to the motion of the receiver).
- 7. The SI unit of frequency; one hertz (Symbol Hz) equals one vibrations per second.
