Looking at this section, I can see questions 6 and 7 about frequency:
6. What is the definition of frequency?
- Frequency is the number of complete cycles (wavelengths) that pass a given point per unit of time. It's typically measured in Hertz (Hz), which represents cycles per second.
7. How can you tell by looking at it if a wave has high or low frequency?
- You can tell by looking at how many wavelengths fit into a given space. A wave with more wavelengths packed together (higher density of waves) has a higher frequency, while a wave with fewer wavelengths spread out over the same space has a lower frequency.
Now let me address the "Frequency Connection" section about family members' voices:
The text states: "There are three members of a family. The dad has a deep, low voice. The mom has a medium-high voice, and the baby has the highest voice."
This means:
- Dad's voice = lowest frequency
- Mom's voice = medium frequency
- Baby's voice = highest frequency
Based on my earlier analysis of the waves:
- Wave 1 has the highest frequency (most wavelengths)
- Wave 2 has medium frequency (medium number of wavelengths)
- Wave 3 has the lowest frequency (fewest wavelengths)
Therefore:
8. Which wave belongs to the dad's voice? - Wave 3 (lowest frequency)
9. Which wave belongs to the mom's voice? - Wave 2 (medium frequency)
10. Which wave belongs to the baby's voice? - Wave 1 (highest frequency)
Let me now provide a complete answer to all the questions on the worksheet.
Complete Solution:
Wave Diagram Labels:
A: Crest
B: Wavelength (distance between consecutive crests)
C: Amplitude (height from equilibrium to crest)
D: Trough
E: Wavelength (distance between consecutive troughs)
F: Amplitude (height from equilibrium to trough)
Frequency Section:
1. Wave 1 is approximately 3 wavelengths long.
2. Wave 2 is approximately 2.5 wavelengths long.
3. Wave 3 is approximately 1.5 wavelengths long.
4. Wave 1 has the highest frequency (most cycles in the same space).
5. Wave 3 has the lowest frequency (fewest cycles in the same space).
6. Frequency is defined as the number of complete cycles (wavelengths) that pass a given point per unit of time, typically measured in Hertz (Hz).
7. You can tell if a wave has high or low frequency by looking at how many wavelengths fit into a given space. More wavelengths packed together indicate higher frequency; fewer wavelengths spread out indicate lower frequency.
Frequency Connection:
8. Wave 3 belongs to the dad's voice (lowest frequency, deep voice).
9. Wave 2 belongs to the mom's voice (medium frequency, medium-high voice).
10. Wave 1 belongs to the baby's voice (highest frequency, highest voice).
Parent Tip: Review the logic above to help your child master the concept of properties of waves worksheets.
