A cylindrical glass rod of radius 0.1 m and refractive index √3 lies on a horizontal plane mirror. A horizontal ray of light moving perpendicular to the axis of the rod is incident on it. At what centre to centre distance a second similar rod, parallel to the first, be placed on the mirror, such that the emergent ray from second rod is in line with the incident ray on the first rod and ray emerges from first rod at the height of 0.1 m from mirror ? |
