Simple Camera

When light from an object passes through a lens, it converges to form an inverted image on a frosted screen. This occurs because the lens bends the light rays, bringing them to a focus point. Alternatively, instead of a frosted screen, if we place a photographic film, which is sensitive to light, at the same location, it captures the image by undergoing chemical changes when exposed to light. This process mimics the way traditional cameras work, creating a permanent image that can be developed and fixed. The term "inverted image" means that the captured image appears upside down compared to the actual object.
