Peak or trough 1 of 5 When waves meet a rigid barrier they are reflected 2 of 5 When waves enter shallower water, the wave speed decreases 3 of 5 When waves travel through or around an obstacle, they spread out 4 of 5 When the gap or obstacle is large compared to the wave length then, the waves only spread out by a small amount 5 of 5
