1. Ray Tracing

2. Ray tracing
Steps in ray tracing
1.Draw an arrow parallel to principal axis from the tip
of the object to the mirror, then reflect it passing at
the focus.
2. Draw another arrow from the radius of curvature to
the tip of the object ,and to towards the mirror.

3. Ray tracing
3. The intersection between the two arrows
is the location of the image.
4. The length of an arrow from the principal
axis to its tip its size.

4. case 1. the object is away from the
radius of curvature of the mirror

5. Analysis
When the object is
away from the
radius of curvature
the image is
reduced and

6. Case 2. the object is between the focus
and the radius of the mirror.

7. Analysis
When the object is
between the focus
and the radius of
curvatureits image is
inverted and
enlarged

8. Case 3. the object is between the
mirror
and the focus

9. Analysis
When the object is
between the mirror
and the focus , its
image is upright and
behind the mirror

10. Case 4 The object is at infinity

11. Analysis
When the object is
at infinity its image
is found at the
focus of the mirror.

12. Case 5. The object is at the radius of
curvature

13. Analysis
When the object is at
the radius of
curvature of the
mirror, its image is
found below the

14. Case 6. the object is at the focus

15. Analysis
When the object is
at the focus of the
mirror its image is
found at infinity.

17. Quiz
1. Draw ray tracing that an object is found
between the focus and the radius of the curved
mirror.
2. Where can you locate the image of an object if
it is located away from the radius of the curved
mirror?
3. Locate the image of an object if it is very far
away from the radius of the mirror.
