WebFeb 20, 2024 · The focal length of the lens is the distance from the center of the lens to the spot, given to be 8.00 cm. Thus, f = 8.00cm. 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. This gives P = 1 f = 1 0.0800m = 12.5D.

WebPrincipal Focal Length. For a thin double convex lens, refraction acts to focus all parallel rays to a point referred to as the principal focal point. The distance from the lens to that point is the principal focal length f of the lens. For a double concave lens where the rays are diverged, the principal focal length is the distance at which the back-projected rays …
