The Physics Of A Camera
The Basics
Cameras, at their very basic level, are lightproof boxes that will allow light to enter one place. A camera will open its shutter, which is a doorway into the camera, and allow for a split second of light to be transmitted into the camera. That light contains the image you wish to capture. Since we can only see things that light reflects off of. Once the light hits the back of a camera it will hit a light-sensitive material made of silver nitrate which will cause a chemical reaction that takes place making the places where the light touches the dark and the film will have to remain transparent.
The Convex Lens
Do cameras use a convex lens to take real inverted images?
Cameras take real inverted images using a convex lens. This is because light always travels in a straight line until a light ray hits a medium, in this case, glass. The glass causes the light rays to refract (or bend) which causes them to form inverted on the opposite side of the medium.
