JEE MainPhysicsGeometrical OpticsMCQ+4 / −1
Given is a thin convex lens of glass (refractive index μ\muμ) and each side having radius of curvature RRR. One side is polished for complete reflection. At what distance from the lens, an object be placed on the optic axis so that the image gets formed on the object itself?
  1. A
    R/μR / \muR/μ
  2. B
    R/(2μ−1)R /(2 \mu-1)R/(2μ−1)
  3. C
    R/(2μ−3)\mathrm{R} /(2 \mu-3)R/(2μ−3)
  4. D
    μR\mu \mathrm{R}μR
