- 2. the propagation of a disturbance through a medium
- 4. occurs whenever successive impulses are applied to a vibrating object in rhythm with its natural frequency.
- 6. a wiggle in time
- 8. Vibration is at right angles(sideways) to wave travel
- 10. Vibration is in the direction of travel
Down
- 1. The time it takes for a complete vibration
- 3. composed of perpendicular electric and magnetic fields that vibrate perpendicular to the direction of wave travel.
- 5. electromagnetic waves created by vibrating electric charges with frequencies that fall within the range of sight.
- 7. The number of to-and-fro vibrations in a given time
