Section of a refracting surface is shown in figure The section is symmetrical about x axis Refractive index of medium on right of the surface is n with respect to the medium on left of the surface Parallel monochromatic light rays are incident on the surface as shown in figure and the refracted rays are focused at F at a distance f from origin O of the co ordinate system shown in figure The equation y x of shape of the section shown is found to be n 1 x n y Bn n 1 fx 0 Find B 2 y F X
