Here's a more detailed explanation:
* Refraction occurs because light travels at different speeds in different mediums. For example, light travels faster in air than it does in water.
* When light enters a new medium at an angle, one side of the light wave slows down before the other side. This difference in speed causes the wave to bend, changing its direction.
* The amount of bending depends on the angle at which the light enters the new medium and the difference in speed between the two mediums.
Here are some examples of refraction in action:
* A straw in a glass of water: The straw appears bent because the light from the straw is refracted as it passes from the water to the air.
* A rainbow: Rainbows are formed when sunlight is refracted and reflected by water droplets in the air.
* Lenses in eyeglasses and cameras: Lenses use refraction to focus light and create images.
