Consider how a converging lens produces a virtual image opposed to a real image.

a. Would the virtual image be upright or inverted? Is it larger or smaller than the object itself?

b. Can you observe this image on a screen placed in front of the lens? Explain

c. Suppose you move the object closer to the lens. Is the image upright or inverted? Is it larger or smaller than the object itself?

d. If the object is closer to a converging lens than the focal point, is it possible for the image to be smaller than the object?

e. What simple optical device uses a converging lens in this way?

Homework Answers

Answer #1

a) For a converging lens, the virtual images will be upright and larger than the object

---------------

b) As light rays from virtual image do not converge , therefore, a virtual image cannot be projected on a screen.

---------------

c) as we move the object closer to the lens, the image size keeps decreasing but image always stays upright,

--------------

d) If the object is closer to a converging lens than the focal point, it is not possible for the image to be smaller than the object

---------------

e) A magnifier can be seen as a device which makes use of this phenomena

A 1.8 cm tall object is placed 5 cm to the left of a converging lens (lens #1) with a focal length of 1.3 cm. To the right of this converging lens is a diverging lens (lens #2) that has a focal length of 2.6 cm. The diverging lens is placed 22.4 cm from the converging lens. Where is the final image, is it real or virtual, and is it upright or inverted?

The focal point on either side of the lens is marked by a small “x”. You will notice that when you move the object (on the left), the real image (on the right) moves as well. What happens to the real image as you move the object toward the lens? Is the image upright or inverted? As you move the object inside of the focal point, you should notice that the rays on the right side of the lens start...
