Textbook Question
Chapter 10.5, Problem 1cT
Suppose that you placed a very small bulb at the location of the image in part B.
How would the rays from the bulb that have passed through the lens be oriented? Draw a diagram to illustrate your answer. Explain.
The point of intersection of the principle axis and the image of a very distant object is called the focal point. The distance between the center of the lens and the focal point is called the focal length.

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.

The diagram below shows the situation described in the problem. The focal length of the lens is labeled f; the scale on the
optical axis is in centimeters. Draw the three special rays, Ray1, Ray2, and Ray3 as described in the Tactics Box above,
and label each ray accordingly. Draw the rays from the tip of the object to the center vertical axis of the lens. Do not draw
the refracted rays.
Draw the vectors for the incident rays starting at the tip of the object to the center vertical axis of the lens. The
location and orientation of the vectors will be graded.

Ray3 Ray though center of lens
Ray2 Ray through near focal point
Rayl Ray parallel to axis
