Plane surface of a thin planoconvex lens reflects `50%` of light, while the curved surface is completely transparent, if final image of `O` after refraction through lens coinsides with the image formed due to partial reflection from plane surface. if distance (in m) between `O` and lens is x then find `x//4`
