You are given three lenses L_(1),L_(2) and L_(3) each of focal length 10 cm. An object is kept at 15 cm in front of L_(1), as shown. The final real image is formed at the focus 'T' of L_(3). Find the separations between L_(1),L_(2) and L_(3).

You are given three lenses L_(1),L_(2) and L_(3) each of focal length 20 cm. An object is kept at 40 cm in front of L_(1), as shown. The final real image is formed at the focus 'I' of L_(3). Find the separations between L_(1),L_(2) and L_(3).

Consider three converging lenses L_1, L_2 and L_3 having identical geometrical construction. The index of refraction of L_1 and L_2 are mu_1 and mu_2 respectively. The upper half of the lens L_3 has a refractive index mu_1 and the lower half has mu_2 . A point object O is imaged at O_1 by the lens L_1 and at O_2 by the lens L_2 placed in same position . If L_3 is placed at the same place.
