Problem 32
Use a ray diagram to determine the approximate location of the image produced by a convex lens when the object is at a distance of \(\frac{1}{2} f\) from the lens. Is the image upright or inverted? Is the image real or virtual?
Problem 33
Use a ray diagram to determine the approximate location of the image produced by a concave lens when the object is at a distance of \(\frac{1}{2}|f|\) from the lens. Is the image upright or inverted? Is the image real or virtual?
Problem 34
A concave lens has a focal length of \(-32 \mathrm{~cm}\). Find the image distance and the magnification that result when an object is placed \(23 \mathrm{~cm}\) in front of the lens.
