Across
- 4. the unit for frequency
- 7. A ____________ wave has particles oscillating at right angles to the direction of wave travel
- 8. A ______________ wave has particles oscillating in parallel to the direction of wave travel
- 10. the to-and-fro movement of particles in a wave
- 11. the time taken for one wave oscillation or 1 / frequency of wave
- 12. the distance between two similar points on a wave or the length of one wave cycle
Down
- 1. A line that joins all the peaks of a transverse wave or compressions of a longitudinal wave
- 2. regions where the waves are bunched up or tightly packed together
- 3. the number of waves completed or passing any point per second
- 5. regions where the waves are stretched out or loosely packed
- 6. the maximum displacement of the wave from its rest position or size of a wave
- 9. ___________ of wave = frequency x wavelength
