An object, pointing upwards, is placed outside the focal point F2 of a thin diverging lens. A
student is using the diagram shown above and the graphical method to predict the image of the
arrow. To draw a principal ray, which direction should the student follow?
O Draw a ray from point Q through F, to the lens, then bend it so it is horizontal.
O Draw a horizontal ray from point Q to the lens, then bend it so it appears to diverge from F2.
O Draw a ray from point P to any position on the lens, then bend it so it is horizontal.
Draw a ray from point Q to the center of the lens, then bend it so it is horizontal.
An object O is placed at the location shown in front of a concave spherical mirror.
Use ray tracing to determine the location and size of the reflected image. As you
work, keep in mind the following properties of principal rays:
Part A
Trace the path of a ray emitted from the tip of the object through the focal point of the mirror and then the reflected ray that results. Start by extending the existing ray emitted from the tip of the object.
Then create the reflected ray.
1. A ray parallel to the axis, after reflection, passes through the focal point
Fof a concave mirror or appears to come from the (virtual) focal point of
a convex mirror.
2. A ray through (or proceeding toward) the focal point Fis reflected
parallel to the axis.
3. A ray along the radius through or away from the center of curvature C
intersects the surface normally and is reflected back along its original
path
4. A ray to the vertex Vis reflected, forming equal angles with the optic
axis.

Problem 9: Two converging lenses with focal lengths of 40 cm and 20 cm are 10 cm apart. A
2.0 cm tall object is 15 cm in front of the 40 cm focal length lens.
a. Use ray tracing to find the position and height of the image. Determine the image
distance and image height by making accurate measurements on your diagram.
Calculate the image height and position relative to the second lens. Compare with
your ray-tracing answers in part a.
b.
c.
Clearly mark the object, image, object distance, image distance and focal length for
both the lenses.
d. Show all your calculations.
e. Write down the image characteristics of each image.
