WebbWatch on. The working principle of a standard camera involves using a lens to focus an image onto a light-sensitive material such as film or a digital image sensor. Light enters the camera through the lens, which is made up of a collection of tiny curved lenses that bend and focus the incoming light onto the image plane. Webb6 maj 2024 · Principle of Simple Microscope A simple microscope works on the principle that when a tiny object is placed within its focus, a virtual, erect, and magnified image of the object is formed at the least distance of distinct vision from the eye held close to the lens.
