Ray diagram in convex mirror

This presentation will help

1. Ray diagram construction in convex mirrors Presented by Obina Johnson Okeny [email protected]

2. The path of three rays that are known is used construct the diagram. These are: Rays traveling parallel to the principal axis are reflected and appear to be coming from the principal focus. Rays going towards the principal focus are reflected parallel to the principal axis. Rays going toward the centre of curvature are reflected back along their own path

3. (a) Rays parallel to the principal axis are reflected and they appear to come from the principal focus. C F P

4. (b) Rays moving towards the principal focus (F) will move parallel to the principal axis after reflection. C F P

5. (c) Ray going towards the centre of curvature (C) are reflected back along their own paths because they are normal to the mirror. C F P

6. I am parallel to the principal axis I am reflected and appear to be coming from F. O C F I I am going towards C. I am reflected back along my own path. I am going towards F I am reflected parallel to principal axis I am the principal axis I am the object I am extended backwards by dotted lines because I am virtual Now let us draw a ray diagram. P

7. Now do some practice by placing the object nearer or further away from the mirror. What is the nature of the image formed in each case? Good luck!
