Q. What is refraction?
Top Answer
Solution:
Refraction is the bending of light when it moves from one material to another. This happens because light changes its speed as it passes through different materials.
Each material, like air, water, or glass, has a property called optical density. Light travels at different speeds in these materials. When the speed of light changes, its direction also changes, causing it to bend.
For example, when you put a pencil in a glass of water, it looks bent. This happens because light changes speed when moving from air to water.
Refraction is used in many devices, like cameras, microscopes, and telescopes, to help focus and magnify images. It also helps us understand natural phenomena like mirages and rainbows.
