L1 is a convex lens of focal length 3f and L2 is a concave lens of focal length f. The two are placed a distance 2f apart. The principle axis of two lens are parallel, but a distance h apart, as shown in Fig. A parallel beam is incident on L1 . The emergent beam, after refraction at both L1 and L2 , is
(1) A parallel beam parallel to axis of L1 and L2
(2) A parallel beam, making an angle of tan-1 (h/y), in the anticlockwise direction, with the principal axis
(3) A parallel beam, making an angle of tan-1 (h/y) , in the clockwise direction, with the principle axis
(4) A divergent beam
