The figure below shows a thin converging lens for which the radii are R₁ = 9.31 cm and R2 = -10.8 cm. The lens is in front of a concave spherical mirror of radius R = 6.58 cm. If its focal points F1 and F2 are 4.62 cm from the vertex of the lens: 10a Determine its index of refraction. Answer 2.08 Show feedback 1 10b If the lens and mirror are 20.5 cm apart and an object is placed 8.3 cm to the left of the lens, determine the position of the final image relative to the lens (Positive values are to the left). Answer Show feedback 10c What is its magnification as seen by the eye in the figure?
