Time Left :

1)	A beam of light composed of red and green rays is incident obliquely at a point on the face of a rectangular glass slab. When coming out on the opposite parallel face, the red and green rays emerge from (1) Two points propagating in two different non-parallel directions (2) Two points propagating in two different parallel directions (3) One pointspropagating in two different directions (4) One points propating in the same direction

2)	$The refracting index of the material of a prism is and its refracting angle is 30degree. One of the refracting surfaces of the prism is made a mirror inwards. A beam of monochromatic light entering the prism from the other face will retrace its path after reflection from the mirrored surface if its angle of incidence on the prism is(1) 45degree (2) 60degree (3) 0degree (4) 30degree$

4)	$A light ray is incident perpendicular to one face of a 90degree prism and is totally internally reflected at the glass-air interface. If the angle of reflection is 45degree, we conclude that the refractive index n (1) n lesser than 1/Route of 2 (2) n greater than Route of 2 (3) n lesser than 1/Route of 2 (4) n greater than Route of 2$

5)	A plano-convex lens of refractive index 1.5 and radius of curvature 30 cm is silvered at the curved surface. Now this lens has been used to form the image of an object. At what distance from this lens an object be placed in order to have a image of the size of the object? (1) 20 cm (2) 30 cm (3) 60 cm (4) 80 cm
