### Understanding Standing Waves

#### Wave Behavior on a String

##### Part A: Analysis of Wave Positions

**Question:**
For \( t \ge 0 \), what are the earliest times, in terms of the wave's period \( T \), that points B, C, and D reach the positions shown?  
**Express your answer in terms of \( T \) separated by commas.**

\[ t_B, t_C, t_D = \]

**Submission Interface:**
- Submit your answers using the provided fields.
- You may use the math input features to ensure proper formatting.

##### Diagram Explanation

**Figure:**
The diagram labeled as "Figure 1" displays a standing wave on a string. The string is anchored at both ends. Points A, B, C, and D are marked on the string, indicative of different positions along the wave at time \( t = 0 \).

1. **A and B:**
    - Positioned at the peaks of the wave (antinodes), indicating maximum displacement.
2. **C and D:**
    - Positioned at the troughs of the wave (nodes), representing points of no displacement.

The figure visually aids in identifying the points B, C, and D to evaluate their position changes over time. Understanding the movement of these points helps in analyzing the wave behavior.

**Conclusion:**
This information will help you determine the exact times \( t_B, t_C, \) and \( t_D \) for the specified points in terms of the wave's period \( T \). Ensure to provide your answer in the format specified.
