5. Reflection from a Convex Mirror
Principal Axis C P

6. Rules of Reflection Incident ray parallel to principal axis
Incident ray passing through center of curvature
Incident ray passing through focus

7. Image is real, diminished and inverted
Object at infinity
Image at focus
Image is real, diminished and inverted C F P

8. Object beyond C Image between center of curvature and focus
Image is real, diminished and inverted C F P

9. Object at C Image at radius of curvature
Image is real, of the same size and inverted C F P

10. Object between C and F Image beyond radius of curvatureP F
Image beyond radius of curvature
Image is real, magnified and inverted

11. Image is real, highly magnified and inverted
Object at F C F P
Image at infinity
Image is real, highly magnified and inverted

12. Object between F and P Image inside the mirror
Image is virtual, magnified and erect C F P

13. Object at infinity Image at focus (inside the mirror)P
Image at focus (inside the mirror)
Image is virtual, diminished and erect

14. Object at a finite distanceP F
Image between focus and the mirror (inside the mirror)
Image is virtual, diminished and erect

15. Mirror Formula Sign Convention
Object is always placed to the left of the mirror
Distance measured upwards from the principal axis
+ve distance
Against the direction of incident light
-ve distance C F P
origin
Distance measured downwards from the principal axis
-ve distance
In the direction of incident light
+ve distance
1 𝑣 + 1 𝑢 = 1 𝑓
𝑣 = distance of the image from the mirror. 𝑢 = distance of the object from the mirror. 𝑓 = focal length of the mirror.
