Refraction is the bending of light when it passes through different mediums, essential for forming images in optical devices.
Refraction is the process that causes the bending of light when it passes from one medium to another due to the change in speed. This phenomenon is crucial in the functioning of lenses in various optical devices such as microscopes and cameras. When light enters a new medium like a lens, its path is altered, leading to the formation of images through refraction.
