The radii of curvature of the surfaces of a thin converging meniscus lens are R1 = 12.0cmand R2 = 28.0cm . The index of refraction of the lens material is 1.60.
A) Compute the position and size of the image of an object in the form of an arrow 5.00mm tall, perpendicular to the lens axis and 45.0cm to the left of the lens.... This has two answers
B) A second converging lens with the same focal length is placed 3.15m to the right of the first. Find the position and size of the final image
C) Is the final image erect or inverted with respect to the original object?
