Across
- 2. A dotted line drawn perpendicular to the surface of the refracting of reflecting wave
- 6. The time for a particle on a medium to make one complete vibrational cycle
- 7. There are two types of this
- 8. A material that transfers energy
- 10. Rate of change in direction and position of an object in motion
- 12. It is equal to 1 cycle per second
- 13. The change of a wave's direction passing from one medium to another
- 14. A surface separating two phases of matter
- 15. Radio waves are an example of this type of wave
Down
- 1. Measured in Hertz
- 3. Distance between the crest/trough and equilibrium
- 4. These waves travel through the layers of the Earth
- 5. An example of a longitudinal wave
- 9. Distance between two crests/troughs
- 11. Ultrasound waves are an example of this type of wave
