When light goes into a lens, its trajectory shifts due to the contrast in the thickness of the two media. This controlled bending of light allows lenses to focus incoming rays onto a specific point, creating a clear and magnified image.
The shape of a lens influences the extent to which light is bent. Convex lenses, which are thicker in the middle, concentrate incoming rays, while concave lenses, which are thinner in the middle, spread out rays.
