the focal length of the two thin convex lenses is the same`=f`They are separated by a horizontal distance`3f`and their optical axes are displaced by a vertical separation`'d'(dltltf)` .Taking the origin of coordinates`O`at the centre of the first,lens ,find the xand y coordiates of the point where a parallel beamof rays coming from the left finally get focused?
