Coupled Oscillating particles. Masses are connected with springs. Strength of springs, size of masses, distance between masses and type of pulses are examined.
Demonstrates how to produce great pulses on a snakey spring.
Shows pulses moving back and forth on a snakey with two fixed ends.
Shows a snakey spring oscillating in the first 5 modes. (Fundamental and first 4 overtones.)
Shows pulses from snakey to slinky.
Shows fixed end reflection on a slinky.
Shows free end reflection on a snakey spring.
Shows reflection and transmission of a pulse traveling from a snakey (more dense) to a slinky (less dense).
Shows reflection and transmission of a pulse traveling from a slinky (less dense) to a snakey (more dense).
Using a plastic slinky connected to a metal slinky shows reflection and transmission at higher to lower and lower to higher density boundaries. Also shows two pulses where reflected and incident superpose.
Two pulses are sent down a slinky on opposite sides to demonstrate destructive interference.
Two pulses are sent down a slinky on the same side to demonstrate constructive interference.
