Describe the motion of an unanchored rowboat when a water wave passes. Does the wave move the boat forward? 2. Contrast how you would move a spring to make a transverse wave with how you would move a spring to make a longitudinal wave. 3. Identify evidence that seismic waves transfer energy without transferring matter. 4. Identify a mechanical wave that is also a longitudinal wave.
Understand the Problem
The questions are focused on understanding different types of wave motions and behaviors, particularly in a physical context involving water and springs. They require descriptive and analytical responses related to motion and energy transfer in waves.
Answer
1. Oscillates without moving forward. 2. Up-down for transverse, back-forth for longitudinal. 3. Energy transferred without moving matter. 4. Sound wave.
- An unanchored rowboat oscillates up and down as a water wave passes, but it does not move forward. 2. Move a spring up and down for a transverse wave, and back and forth for a longitudinal wave. 3. Seismic waves transfer energy over vast distances without moving matter, shown by buildings being affected without ground relocation. 4. Sound waves are mechanical and longitudinal.

More Information
Water waves primarily cause vertical boat movement, not horizontal displacement. For seismic waves, the energy impacts without matter displacement demonstrates wave transmission. Sound, being both mechanical and longitudinal, moves via particle compression and rarefaction.
Tips
A common mistake is thinking waves carry matter with them; they only transfer energy. Visualizing particle motion helps avoid confusion.
