Image formation refers to the process by which an image is created using lenses or mirrors. It involves the interaction between incoming rays of light and optical elements.
Related terms
Convex Lens/Mirror: These optical elements converge incoming parallel rays towards each other, forming real images.
Concave Lens/Mirror: These optical elements diverge incoming parallel rays away from each other, forming virtual images.
Focal Length: The focal length is the distance between the lens/mirror and its focal point, where parallel rays converge or appear to converge.
