As part of a piece of optical apparatus to be used in air, you need to design a thin lens
having faces with radii of curvature of magnitude 24 cm each. When an object 32 mm tall
is placed 30 cm from this lens, it must form a real image 60 cm from the lens.
(a) What must be the index of refraction of the lens material?
(b) What is the height of the image of the object? Is it upright or inverted; is it real or
virtual?
