- An object is placed in front of a converging lens at an object distance of twice the focal length of the lens. Sketch a ray diagram and compare the image and object distances. Repeat with two more ray diagrams, using different focal lengths and still making the object distance twice the focal length. Can you draw any conclusions by comparing the object distance and the image distance?arrow_forwardSketch ray diagrams for a spherical convex lens with objects at (a) Do 2f, (b) 2f Do f, and (c) Do f.

An object is placed on the bisector between the minors. Construct a ray diagram as in Figure 2.4 to show how many images are formed. Figure 2.4 Two minors can produce multiple images. (a) Three images of a plastic lead are visible in the two minors at a right angle. (b) A single object reflecting from two minors at a right angle can produce three images, as shown by the greet, purple, and red images.arrow_forward

Look backward and forward through a pair of eyeglasses and comment on whether they are thin lenses.arrow_forwardA magnifying glass forms an image 10 cm on the opposite side of the lens from the object, which is 10 cm away.

Assume thin-lens approximation. (Hint: Pick a point P on the given ray in each case. Treat that point as an object. Now, find its image Q. Use the rule: All rays on the other side of the lens will either go through Q or appear to be coming from Q.)arrow_forwardIn a reflecting telescope the objective is a concave mirror of radius of curvature 2m and an eyepiece is a convex lens of focal length 5 cm.
