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 f
- 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 a is equivalent to a and sin (a + b) = a+b , where a and b are angles. The final image is
- NOTE: a and b are alpha and beta respectively
