A lens produces a real image of a real object.

  1. Is the image formed is inverted or upright?
  2. Is the lens diverging or converging?
  3. Is the image enlarged or reduced? 
  4. If two convex lenses identical in size and shape are manufactured from glass with two different indexes of refraction, would the focal length of the lens with greater index of refraction (lens 1)be larger or smaller than that of lens 2?

Indicate the single lens type (converging or diverging) and objectposition that will lead to the following kind of images. If
no single lens system can produce the particular image indicatethat this is so.
A) virtual, enlarged, upright image.
B) real, enlarged, inverted image.
C) virtual, reduced in size, upright image.
D) real, upright, enlarged image.
E) virtual, enlarged, inverted image.
F) real, reduced in size, inverted image.
G) tiny inverted image very near focal point.
H) huge image at “infinity”.
I) real, inverted image that is the same size as the object.

The image produced by a diverging lens is upright and virtual no matter where the object is in front of the lens. However that for a converging less, the displacement of the object relative to the focal length determines whether the image is virtual or real, upright or inverted and larger or smaller than the object. Examine the convex and concave mirror. Is diverging more like a convex mirror or a concave mirror?

A converging lens with a focal length of 50 cm is placed 40 cm to the left of a diverging lens with a focal length of -20cm. An object with a height of 1.5cm is placed 75 cm to the left of the converging lens. (a) Where is the final image formed? (b) Is this image real or virtual? (c) Is the image upright or inverted? (d) What is the size of the final image?
