The figure shows an arrangement of an equiconvex lens made of glass of refractive index, \mu_2 = 1.5 and a concave mirror. Medium to the left of the lens has refractive index \mu_1 = 1.2 and that to the right of the lens has refractive index \mu_3 = 2.0. A pointobject O is placed on the principal axis at a distance of 40 cm from the lens such that the final image is formed at the position of the object itself. The focal length of the concave mirror is 40 cm and the focal length of lens in air is 20 cm. Findthe value of d/6 (in cm)

The figure shows an arrangement of an equiconvex lens made of glass of refractive index, µ2 = 1.5 and a concave mirror. Medium to the left of the lens has refractive index µ1 = 1.2 and that to the right of the lens has refractive index µ3 = 2.0. A pointobject O is placed on the principal axis at a distance of 40 cm from the lens such that the final image is formed at the position of the object itself. The focal length of the concave mirror is 40 cm and the focal length of lens in air is 20 cm. Findthe value of
