Here's a breakdown:

* Diffraction: This phenomenon occurs when waves encounter an obstacle or pass through an opening. The waves spread out as they pass the edge of the obstacle or opening, causing them to bend.

* Wave Interference: Diffraction is closely related to wave interference. As the waves spread out, they interfere with each other, creating patterns of constructive and destructive interference.

Examples of Diffraction:

* Light passing through a narrow slit: This creates a pattern of bright and dark fringes on a screen behind the slit.

* Sound waves bending around a corner: This is why you can still hear someone talking even if they are hidden behind a wall.

* Water waves passing through an opening: The waves spread out and change direction as they pass through the opening.
