![### Wave Properties and Analysis
#### 2. Amplitude Comparison
The amplitude of a sound wave is to its loudness as the amplitude of a light wave is to its
[Answer: Brightness].
#### 3. Energy Transfer in Waves
As a sound wave travels through the air, there is a net transfer of:
a. Energy, only
b. Mass, only
c. Both mass and energy
d. Neither mass nor energy
[Correct Option: a. Energy, only]
#### 4. Wave Analysis Diagram
In the diagram below:
- **a. Find the amplitude of each wave.**
- The amplitude is the maximum displacement from the equilibrium position, which can be measured as the height from the x-axis to the peak of the wave in meters.
- **b. Find the wavelength of each wave.**
- The wavelength is the distance between two consecutive points in phase on the wave (e.g., from one peak to the next peak), measured in meters.
- **c. Find the frequency of each wave.**
- The frequency is the number of cycles per second, calculated using the wave's period.
- **d. What is the speed of wave A?**
- The speed of wave A can be found using the formula \( \text{speed} = \text{wavelength} \times \text{frequency} \).
- **e. Which two waves have the same wavelength?**
- By comparing wavelengths visually, identify which waves repeat with the same spatial period.
- **f. Which wave has the longest period?**
- The period is the time taken for one complete cycle, identified by the longest time interval between repeating points.
*Diagram Explanation*:
The graph shows three distinct waves labeled A, B, and C displaying their respective amplitudes, wavelengths, and periods over a 12-meter and 2-second interval.
#### 5. Frequency Calculation
- **What is the frequency of the following wave?**
- The frequency \( f \) can be calculated using the time period \(T\). Here, \( T = 0.10 \, \text{s} \), therefore:
\[
f = \frac{1}{T} = \frac{1}{0.10 \, \text{s}} = 10 \, \text{Hz}
\]
