Column I		Column II
(A)	Intensity of light received by lens.	(P)	Radius of aperture(R).
(B)	Angular magnification.	(Q)	Dispersion of lens.
(C)	Length of telescope.	(R)	Focal length $f_0, f_e$.
(D)	Sharpness of image.	(S)	Spherical aberration.

Two identical prisms of refractive index $$\sqrt{3}$$ are kept as shown in the figure. A light ray strikes the first prism at face AB. Find

(A) the angle of incidence so that the emergent ray from the first prism has minimum deviation;

(B) through what angle, the prism DCE should be rotated about C so that the final emergent ray also has minimum deviation?

IIT-JEE 2005 Mains Physics - Geometrical Optics Question 17 English

(A) = 45$$^\circ$$, (B) = 60$$^\circ$$

(A) = 60$$^\circ$$, (B) = 45$$^\circ$$

(A) = 45$$^\circ$$, (B) = 45$$^\circ$$

(A) = 60$$^\circ$$, (B) = 60$$^\circ$$
