**Educational Content: Understanding Wave Properties** --- ### 3. Wave Energy Transfer **Question:** As a sound wave travels through the air, is there a net transfer of: a. energy, only b. mass, only c. both mass and energy d. neither mass nor energy **Answer:** When a sound wave travels through the air, there is a net transfer of energy only (Answer: a). --- ### 4. Analyzing Waves Below is a diagram with multiple waves labeled A, B, C, and D. **Tasks:** a. Find the amplitude of each wave. b. Find the wavelength of each wave. c. Find the frequency of each wave. d. What is the speed of wave A? e. Which two waves have the same wavelength? f. Which wave has the longest period? **Diagram Explanation:** The diagram shows four waves plotted on a graph. The x-axis represents space or time, labeled as 12 meters and 2 seconds. The y-axis represents displacement. For wave A: - Amplitude: Measure the peak displacement of wave A from the rest position (y = 0). - Wavelength: Measure the distance between two consecutive points in phase (e.g., crest to crest or trough to trough). - Frequency: Calculate based on the number of wavelengths per second. - Speed: Use the formula \( \text{Speed} = \text{Wavelength} \times \text{Frequency} \). Repeat these steps for the waves B, C, and D. For parts: e. Compare the measured wavelengths of each wave and identify which two are the same. f. Consider the wave with the lowest frequency since the period \( T = \frac{1}{\text{Frequency}} \). --- ### 5. Frequency Calculation **Question:** What is the frequency of the following wave? **Diagram Explanation:** The graph shows a wave with displacement on the y-axis (measured in cm) and time on the x-axis (measured in seconds). To find the frequency: - Identify the period (T), which is the time taken to complete one cycle. The period here is 0.10 seconds. - Frequency (f) is the reciprocal of the period: \( f = \frac{1}{T} = \frac{1}{0.10 \text{ s}} = 10
