In this task you are to use the long springs to examine wave interactions. Place a marker on the spring and observe (video this point)
Model constructive interference by sending two pulses with same direction of disturbance
Model destructive interference by sending two pulses with opposite direction of disturbance.
Use the large slinkies to repeat this using longitudinal waves
1. What happened to the position of the marker for each model.
2. Describe your observations for the longitudinal waves, was the interference observable?
3. Describe and explain how this correlated to sound
