Across
- 3. the number of to-and-fro vibrations in a given time period
- 4. a wave that requires a medium through which to travel
- 8. is a wiggle or movement
- 9. a wave caused by a disturbance in electric and magnetic fields that do not need a medium
- 10. is the highest point
Down
- 1. vibration is in the direction of travel(parallel) to travel
- 2. vibration is at right angles (perpendicular) at wave travel
- 5. is a wiggle in space and time a disturbance that travels from one place to another transporting energy
- 6. is the lowest point
- 7. describes how fast the disturbance moves through medium
