Web- The focal length is positive (f > 0) for a converging lens and negative (f . 0) for a diverging lens. The thin lens formula is then expressed as follows, `1/d_0 + 1/d_1 = 1/f` Calculation example : case of a converging lens. The purpose is to calculate the position of the image of an object which is 20 cm away from a converging lens. WebApr 7, 2024 · 1.The focal length of a lens, made up of glass, is 5 cm in air. What would be the focal length of the same lens in water? The refractive indices of glass and water are 1.51 and 1.33 respectively. Solution: The radii of curvature of the lens are R1 and R2. The focal length of the lens in the air is fa= 5 cm.
