Suppose that a hand holding the first coil of a slinky is moved back-and-forth two complete cycles in one second. ![]() ![]() But the act of continually vibrating the first coil with a back-and-forth motion in periodic fashion introduces a wave into the slinky. A single back-and-forth vibration of the first coil of a slinky introduces a pulse into the slinky. This vibration creates a disturbance that moves through the slinky and transports energy from the first coil to the last coil. In that lesson, it was mentioned that a wave is created in a slinky by the periodic and repeating vibration of the first coil of the slinky. The nature of a wave was discussed in Lesson 1 of this unit.
