The _________ of a sound wave is the measure of the height of the wave.

Options

A. Oscillation
B. amplitude
C. frequency
D. time period

Answer

To answer the question, "The _________ of a sound wave is the measure of the height of the wave," we need to fill in the blank with the correct term that describes the height of a sound wave.

### Step-by-Step Solution:

1. **Understanding Sound Waves**: Sound waves are vibrations that travel through a medium (like air, water, or solids). They can be represented graphically, where the height of the wave corresponds to certain properties of the sound.

2. **Identifying Key Terms**: In the context of sound waves, the height of the wave is crucial for understanding its characteristics. The height refers to how far the wave moves from its rest position.

3. **Defining Amplitude**: The height of a sound wave is specifically referred to as the "amplitude." Amplitude is defined as the maximum displacement of points on a wave from their rest position (mean position).

4. **Conclusion**: Therefore, the correct term to fill in the blank is "amplitude."

Final Answer: The **amplitude** of a sound wave is the measure of the height of the wave.
