Nodes are the points of

Options

A. zero displacement
B. maximum displacement
C. maximum amplitude
D. maximum acceleration

Explanation

**Step-by-Step Solution:**

1. **Understanding Nodes**: Nodes are specific points in a standing wave where the displacement of the medium is always zero. This means that at these points, the wave does not oscillate.

2. **Characteristics of Nodes**: At the nodes, the amplitude of the wave is zero. This implies that there is no movement of the particles of the medium at these points.

3. **Visual Representation**: If you visualize a standing wave created by a vibrating string, you can identify the nodes as points that remain stationary while the rest of the wave oscillates.

4. **Acceleration at Nodes**: Since the particles at the nodes do not move, their acceleration is also zero. Acceleration is a measure of how quickly the velocity of an object changes, and if there is no movement, there can be no acceleration.

5. **Conclusion**: Therefore, nodes are points of zero displacement and zero amplitude in a standing wave. They do not exhibit maximum displacement or maximum acceleration.

**Final Answer**: Nodes are points of zero displacement in a standing wave.
