Question

The diagram shows a silvered equiconvex lens. An object of length 1 cm has been placed in the front of the lens. What will be the final image properties? The refractive index of the lens is mu and the refractive index of the medium in which the lens has been placed is 2mu. Both the surface have the radius R

  1. Half size, erect and virtual    
  2. same size, erect and real    
  3. same size, erect and virtual    
  4. none    

The correct answer is: same size, erect and virtual
