The word KVPY is written on a board and viewed through different lenses such that board is at a distance beyond the focal length of the lens.Ignoring magnification effects, consider the following statements:(I) First image has been viewed from the planar side of a plano-convex lens and second image from the convex side of a plano-convex lens.(II) First image has been viewed from the concave side of a plano-concave lens and second image from the convex side of a plano-convex lens.(III) First image has been viewed from the concave side of a plano-concave lens and second image from the planar side of a plano-convex lens.(IV) First image has been viewed from the planar side of a plano-concave lens and second image from the convex side of a plano-convex lens.Which of the above statements are correct?(a) All statements are correct(b) Only statement III is correct(c) Only statement IV is correct(d) Only statements II, III and IV are correct |
Answer» (d) Only statements II, III and IV are correct A plano-concave lens is a diverging lens and a plano-convex lens is a converging lens. Image formed by a plano-concave lens is always erect and virtual. Image formed by a plano-convex lens is real and inverted when object is placed at a distance larger than focal length of lens. Plano-convex lens is a converging lens. Hence, image formed by a plano-convex lens is inverted. So, all statements are correct. |
