Chapter 10.6, Problem 3aT
Obtain convex lens. Use the lens as a magnifying glass, that is, to make an object such as a pencil appear larger. Start with the lens very close to the object.
Which is farther from you: the image of the object?
Where is the object relative to the lens and its focal points? (For example, is the object distance greater than, less than, or equal to the focal length of the lens?)

Each of the parts in this problem has a description of an object and an optical device (a lens or a mirror). A sketch of each part is shown below in which the centers of the mirrors and the focal points of the lenses are shown. The radius of curvature of each mirror is R, and the focal length of the lenses is f. For each part, determine:
the image is real, virtual, or no image is formed
the image is on the same side of the optical device as the object or the opposite side (if there is no image, indicate this)
if at image is formed, on which side of the optical device must the observer be in order to see it
A. An object is on the right side of a spherical mirror, a distance s > R from the mirror. The reflective surface of the mirror faces the object and is concave.The image is ---Select--- real virtual neither (no image is formed)The image is ---Select--- on the same side of the mirror as the object on the opposite side of the mirror from the object neither (no image is…
An object is placed 10 m before a convex
lens with focal length 5.2 m. Another concave
lens is placed 15.6 m behind the first lens with
a focal length
-7.2m (see the figure below).
Note: Make a ray diagram sketch in order
to check your numerical answer.
At what distance is the first image from the
first lens?
Answer in units of m.
What is the magnification of the first image?
At what distance is the second image from the
second lens?
Answer in units of m.
What is the magnification of the final image,
when compared to the initial object?
An object is 12.0 cm from a converging lens (focal length = 15.0 cm). Determine the image magnification.
Enter the numerical part of your answer to two significant figures.
Hint: Remember that the sign of the magnification is significant.
