- 2. electromagnetic waves created by vibrating electric charges with frequencies that fall within the range of sight.
- 4. is a wiggle in space and time—a disturbance that travels from one place to another transporting energy.
- 6. occurs whenever successive impulses are applied to a vibrating object in rhythm with its natural frequency.
