A double convex lens ( R1 = R2 = 10cm) (u= 1.5) having focal length equal to the focal length of a concave mirror. The radius of curvature of the concave mirror is (a) 10 cm (b 20 cm (c) 40 cm (d) 15 cm

Step 1
5 Using the lens maker's formula: 1/F = (u - 1) * (1/R1 - 1/R2) Substitute the values: 1/F = (1.5 - 1) * (1/10 - 1/10) 1/F = 0.5 * 0 1/F = 0 Therefore, the focal length of the double convex lens is 0 cm. ** Show more…

A convex lens of focal length $15 \mathrm{~cm}$ is placed in front of a convex mirror. When the object is placed at $\mathrm{O}$, the image coincides with it. The radius of curvature of mirror is (a) $20 \mathrm{~cm}$ (b) $40 \mathrm{~cm}$ (c) $15 \mathrm{~cm}$ (d) $55 \mathrm{~cm}$
The focal length of a convex mirror is 20 cm its radius of curvature will be (a) 10 cm (b) 20 cm (c) 30 cm (d) 40 cm

The radii of curvature of the two surfaces of a lens are 20 cm and 30 cm, and the refractive index of the material of the lens is 1.5. If the lens is concavo-convex, then the focal length of the lens is: A. 24 cm B. 10 cm C. 120 cm D. -120 cm
