During the formation of a stationary wave, the medium is broken into loops between equally spaced points called………………

Explanation

**Step-by-Step Solution:**

1. **Understanding Stationary Waves**: A stationary wave, also known as a standing wave, is a wave that does not propagate through the medium. Instead, it oscillates in place, creating a pattern of nodes and antinodes.

2. **Identifying the Structure of Stationary Waves**: In stationary waves, the medium is divided into segments that appear as loops. These loops are formed due to the interference of two waves traveling in opposite directions.

3. **Defining Nodes**: The points in a stationary wave where the amplitude is always zero are called nodes. At these points, there is no movement of the medium, and they are spaced equally along the wave.
