The distance between two consecutive points in the same phase is called

Options

A. pitch
B. velocity
C. wavelength
D. period

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the term that describes the distance between two consecutive points in the same phase of a wave.

2. **Identifying the Key Concept**: In wave motion, points that are in the same phase have the same displacement and are moving in the same direction at the same time.

3. **Defining Wavelength**: The wavelength is defined as the distance between two consecutive points that are in the same phase. This means that if you take any two points on a wave that are at the same position in their cycle (e.g., two crests or two troughs), the distance between them is the wavelength.

4. **Evaluating the Options**:
- **Pitch**: This is related to the frequency of sound and is not a measure of distance. Thus, it is incorrect.
- **Velocity**: This refers to the speed of the wave and is also not a measure of distance. Thus, it is incorrect.
- **Wavelength**: This is the correct term as it describes the distance between two points in the same phase.
- **Period**: This refers to the time it takes for one complete cycle of the wave to pass a given point and is not related to distance. Thus, it is incorrect.

5. **Conclusion**: The correct answer is "wavelength," as it specifically refers to the distance between two consecutive points in the same phase of a wave.

**Final Answer**: The distance between two consecutive points in the same phase is called **wavelength**.
