What is the phenomenon that occurs when two or more waves meet at the same point in space?

The phenomenon that occurs when two or more waves meet at the same point in space is called "Interference".

Here are the steps to understand this phenomenon:

1. Wave Propagation: First, it's important to understand that waves propagate or travel through space. This could be light waves, sound waves, water waves, etc.

2. Wave Interaction: When two or more waves meet at the same point in space, they interact with each other. This interaction is what we call "Interference".

3. Constructive and Destructive Interference: The interference can be constructive (where the wave amplitudes add together to create a wave of larger amplitude) or destructive (where the wave amplitudes cancel each other out to create a wave of smaller amplitude or even no wave at all).

4. Resultant Wave: The result of this interference is a new wave that is the sum of the amplitudes of the interacting waves.

5. Continuation of Waves: After the point of interference, the waves continue to propagate as if they had never interacted. This is a characteristic of waves known as superposition.

So, in summary, the phenomenon of two or more waves meeting at the same point in space and interacting is known as "Interference".
