Across
- 2. The region in a longitudinal wave where particles are pushed together
- 3. Type of wave where oscillations are parallel to direction of energy transfer
- 8. Change in direction of waves when they change speed moving between media
- 11. A measurable effect of increased amplitude in sound waves
- 12. The formula linking wave speed, frequency and wavelength
- 14. The bouncing back of waves from a surface
- 15. The number of complete wave cycles passing a point per second
Down
- 1. The time taken for one full cycle of a wave to pass a point
- 4. Type of wave where oscillations are perpendicular to direction of energy transfer
- 5. The maximum displacement of particles from their rest position in a wave
- 6. Unit of frequency, equal to one cycle per second
- 7. The total length of one full wave cycle (crest to crest or compression to compression)
- 9. The region in a longitudinal wave where particles are more spread out
- 10. The part of the ear that vibrates in response to sound waves
- 13. Spreading out of waves after passing through a gap or around an obstacle
