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 focal length of the lens is the distance from the center of the lens to the spot, given to be 8.00 cm. Thus, 25.22 To find the power of the lens, we must first convert the focal length to meters; then, we substitute this value into the equation for power.
