Here's a breakdown:

* Diffraction is the phenomenon where waves spread out as they pass through an opening or around an obstacle. This bending of waves is a result of their wave nature.

* Why it happens: Waves don't travel in perfectly straight lines. Instead, they have a tendency to spread out. When they encounter an obstacle, they bend around the edges.

* Examples:

* Sound waves: You can hear someone talking even if they are behind a wall because sound waves diffract around the wall.

* Light waves: You can see around corners because light waves diffract. This is also why you can see a faint shadow cast by a very small object, even though the light source is far away.
