What is the phase difference between particles being on either side of a node?

Explanation

To determine the phase difference between particles located on either side of a node in a stationary wave, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Nodes in Stationary Waves**:
- A node is a point in a stationary wave where the amplitude is zero. This means that at the node, there is no displacement of the medium.

2. **Visualizing the Stationary Wave**:
...
