Refraction is the bending of light as it passes through different materials, such as air, water, or glass. This occurs because light travels at different speeds in different materials.
Refraction plays a crucial role in our vision. When light enters our eyes, it is refracted by the cornea and lens to focus on the retina, allowing us to see objects clearly. Changes in the shape of the cornea or lens can lead to vision problems.
Refraction is the bending of light as it passes through a material, while reflection is the bouncing of light off a surface. Refraction involves a change in the direction of light, while reflection involves a change in its path.
When light travels from air to water, it slows down and bends, causing objects to appear distorted. This is because the light rays are refracted at different angles as they pass through the water, giving us a distorted view of the object.
Refraction and reflection have many practical applications, such as in eyeglasses, cameras, and telescopes. They are also used in fiber optic cables, which use total internal reflection to transmit light signals over long distances. Additionally, refraction is used in the design of lenses for corrective eye surgery and in the creation of prisms for splitting light into its component colors.
