The figure below shows a thin converging lens for which the
radii are R1 = 9.32 cm and R2 = -11.4 cm. The lens is in front of a
concave spherical mirror of radius R = 7.92 cm. If its focal points
F1 and F2 are 4.60 cm from the vertex of the lens: a)
Determ
ine its index of refraction.
b) If the lens and mirror are 19.7 cm apart and an object is placed
8.21 cm to the left of the lens, determine the position of the
final image relative to the lens (Positive values are to the left).
c) What is its magnification as seen by the eye in the figure?
