What do you understand by the principle of superposition?

Explanation

### Step-by-Step Solution:

1. **Definition of Principle of Superposition**: The principle of superposition states that when two or more waves travel through the same medium, they can pass through each other without being disturbed.

2. **Medium**: Identify the medium through which the waves are traveling. This could be air, water, or any other material substance.

3. **Simultaneous Travel**: The waves must be traveling through the same medium at the same time. This is crucial for the principle to apply.
