ICSE 10th Physics - Problem 10 - Lens in a denser medium

Title: Problem - 10 - Lens in a denser medium. Convex lens in a denser medium acts like a concave lens and concave lens in a denser medium act like a convex lens. The focal length of a lens is not a fixed property—it depends on several physical and geometrical factors. Here’s a clear breakdown: 🔑 Factors Affecting Focal Length of a Lens • Curvature of Lens Surfaces The more curved (steeper) the surfaces, the shorter the focal length. Flatter surfaces increase the focal length. • Refractive Index of Lens Material A higher refractive index (like flint glass) bends light more strongly, reducing focal length. A lower refractive index (like crown glass) results in a longer focal length. • Lens Shape (Convex/Concave) Convex lenses (converging) have positive focal lengths. Concave lenses (diverging) have negative focal lengths. The exact curvature ratio of the two surfaces also matters. • Surrounding Medium Focal length changes if the lens is placed in a medium other than air (e.g., water or oil), because the relative refractive index changes. • Lens Thickness (for thick lenses) In thin lenses, thickness is negligible. In thick lenses, thickness affects the effective focal length due to additional refraction inside the lens. 🔔 Like, Subscribe, and Share!
