15. GRAPHICAL METHOD
FOR MIRRORS

16.  Locating object with the used of ray diagrams
 Ray Diagrams is used for determining the path
taken by light from the object to the mirror to
our eyes

17. CONCAVE MIRRORS
1. An incident ray which is parallel to the principal axis is
reflected through the focus of the mirror.
2. An incident ray which passes through the focus of the
mirror is reflected parallel to the principal axis.
3. An incident ray which passes through the centre of
curvature of the mirror is reflected back along its own
path (since it is normally incident on the mirror).
4. An incident ray which strikes the mirror at its vertex is
reflected such that its angle of incidence with respect to
the principal axis is equal to its angle of reflection.

19. C F V

24. CONVEX MIRRORS
1. An incident ray which is parallel to the principal axis is
reflected as if it came from the virtual focus of the mirror.
2. An incident ray which is directed towards the virtual
focus of the mirror is reflected parallel to the principal
axis.
3. An incident ray which is directed towards the centre of
curvature of the mirror is reflected back along its own
path (since it is normally incident on the mirror).
4. An incident ray which strikes the mirror at its vertex is
reflected such that its angle of incidence with respect to
the principal axis is equal to its angle of reflection.

28. Evaluation:
The diagram below shows a spherical surface that is
silvered on both sides. Thus, the surface serves as
double-sided mirror, with one of the sides being the
concave and one being the convex side. The principal
axis, focal point, and center of curvature are shown.
The region on both sides of the mirror is divided into
eight sections (labeled M, N, P, Q, R, S, T, and W).
Five objects (labeled 1, 2, 3, 4, and 5) are shown at
various locations about the double-sided mirror.

29. 1. The image of object 1 would be located in section
_____.
M N P Q R S T W

30. 2. The image of object 2 would be located in section
______.
M N P Q R S T W

31. 3. The image of object 3 would be located in section
______.
M N P Q R S T W

32. 4. The image of object 4 would be located in section
______.
M N P Q R S T W

33. 5. The double-sided mirror would cause real image to be
formed of objects ________.
a. 1, 2, and 4 b. 1, 2, and 3 c. 3 and 5
d. 4 and 5 e. 3 only
