With neat labelled diagrams, explain the different modes of vibration of a stretched string.

Explanation

To explain the different modes of vibration of a stretched string, we will discuss the fundamental mode and the first two harmonics (overtones) with neat labeled diagrams.

### Step 1: Fundamental Mode (First Harmonic)
In the fundamental mode, the string vibrates in a single segment, creating one antinode at the center and two nodes at the ends.
