Focal length of diverging lenses

WebApr 14, 2024 · A converging beam of rays is incident on a diverging lens. Having passed through the lens the rays intersect at a point $15\,cm$ from the lens on the opposite side. If the lens is removed the point where the rays meet will move $5\,cm$ closer to the lens. The focal length of the lens is WebThe distance from the lens to the principal focus is called the focal length. Concave lenses A concave lens is thinner in the middle than it is at the edges. This causes parallel rays to...
