WebMore quantitatively, since the diverging lens is 28 cm to the right of the converging lens, the object distance is d o = 28 cm + 12 cm = 40 cm; this is the distance between the diverging lens and the image formed by the converging lens. Using the lens equation, we get d i = -10.4 cm. That is, the final image is 10.4 cm to the left of the ... WebDouble convex lens. A double convex lens, also known as a biconvex lens or just convex lens, is curved outwards at both sides of the lens. These are also used to focus light but are preferred when the object is closer to the lens. This is termed finite conjugate in optical physics. An example of the same is microscopy. harry schumilas md https://andysbooks.org
