Instructions: In this activity, you will test two hypotheses for wave motion. Describe which hypothesis you think is accurate and why.

Hypothesis 1: Waves are sets of particles moving together due to their forward momentum.

Hypothesis 2: Waves occur when particles transmit energy to other particles in all directions but don't move far from their original positions.

? Predict:The Gizmo (picture) shows a barrier with a small gap that waves can pass through. Points A and B are equal distances from the gap.
