(2010) -1.0 / 4 KUTTER 4/3 Analytical question 1. Glass thin concave lens (refractive index) -1.5) convex radius of curvature of 20 cm is. The curvature radius of a concave surface is 60 cm. Silver convex is placed on the convex surface and It is placed on the horizontal floor. (a) Where to place a pin on the main axis, so that its image Be made at the same place? (b) If the concave part is filled with water (refractive index 4/3), then Tell me how much the pin will have to move so that the image of the pin is again Made on a pin?
