Here's the list of correct responses based on the questions provided:
1. **Which measure does not change when a wave moves from one medium to another?**
- **Frequency**
2. **Water waves approaching the shore will slow down. Which statement describes another change that occurs?**
- **The wavelength decreases.**
3. **As a wave travels from one medium to another, its wavelength triples. Which statement describes the speed and frequency in the new medium?**
- **The speed will triple, and the frequency will stay the same.** (This is because frequency remains constant when a wave enters a new medium, while speed and wavelength may change based on the medium characteristics.)
4. **Sonar systems used in water send out sound waves that reflect off the environment and then are detected. As water gets denser, the speed of sound in water increases. What would happen to the wavelength of a sonar wave as it moves into water with a 5% higher speed of sound?**
- **The wavelength would increase by 5%.** (Since the frequency remains constant, an increase in speed leads to an increase in wavelength.)
5. **An earthquake sends seismic waves outward from the epicenter. The waves travel through different media in different directions. What will be true for all people who feel the earth shaking?**
- **The earth will rise and fall with the same frequency.** (The frequency of seismic waves will be consistent for all observers since they originate from the same source.)
For the characterization portion:
- **Direct characterization:**
- Tells information about the character's physical appearance
- Uses statements from the narrator
- **Indirect characterization:**
- Requires the reader to make deductions about the character
- Describes the actions the character takes
- Requires the reader to draw conclusions about the character's thoughts or actions
- Requires the reader to think about how other characters react to the character
