Fixed End Reflect
Free End Reflect
What effect does the density of a medium have upon the speed at which waves travel through the medium? Alter the density, run the simulation, and observe the effect upon speed.

Reflection: Fixed End
Reflection: Free End
Relative Density of Medium 1
Select relative densities for Medium 1 and Medium 2. Then run the simulation. Can you determine any behavior patterns associated with a wave crossing a boundary?
What happens when a wave reaches the end of the medium and the last particle is fixed and unable to vibrate up and down? Run the simulation and find out.
Relative Density of Medium 2
What happens when a wave reaches the end of the medium and the last particle is free to vibrate up and down? Run the simulation and find out.
Relative Density of Medium
Investigate … the effect of medium density on wave speed, the reflection of a wave off a fixed end, the reflection of a wave off a free end, and the behavior of a wave crossing a boundary.
