A system is shown in the figure. Light rays from a point object are first deviated by a prism and then focused by a thin lens of focal length ſ. The prism is made of material with refractive index 3/2 and has small apex angle 2° i.e., small angle approximations are valid. sin and sin ( + ) = + , where and Are angles. The final image is |
|||

(a) |
virtual and formed at a distance 2f from the lens |
(b) |
real and formed at a distance 2f from the lens |

(c) |
real and formed at a distance 3 f/2 |
(d) |
real and formed at a distance 3 f from the lens |
