Lenses and Images
(Due at the beginning of lab)
1. What is a virtual image? How is it different than a real image?
The next several questions refer to the lens system shown in the figure below. Initially,
the object is at position A, and the image is formed at position.
(a) To what position (B,C,D, on one of the focal points, or infinitely far away) must
the object be moved in order to cause the change in the image described in each of
the following questions. Explain why moving the object to the position you identify
brings about the required change in the image.

(e) The image becomes smaller.

(f) The image is no longer a real image.

(g) The image is formed at the right hand focal point.

  1. The drawing below shows three principle rays coming from the top of an object. One ray is parallel to the axis until it reaches the lens. A second ray is directed from the top of the object to the center of the lens.The third ray goes from the top of the object through the focal point to the left of the lens. Draw the continuations of the rays on the right hand side of the lens, and locate the image. Is the image real or virtual? Erect or inverted?
