Focal Length + or -?
+ converging lens or mirror
- diverging lens or mirror
Object Distance + or -?
+ if left of lens
- if right of lens
Image Distance + or -?
+ real
- virtual
Plane Mirror Image?
always U V and same size at distance I = -O
Diverging Lenses/Mirrors
everything is smaller, upright, virtual and within the focal length. UVS WNF
DiVex Mirror
DAve Lens
h'/h or s'/s (relative to height or distance)
Converging Mirrors/Lenses
As you move the object further away, the image gets closer to the focal point and smaller.

As you move it closer, the opposite happens.
For Lenses remember:
Real and Virtual sides are flipped & convex and concave are reversed
Formation of Real Image using a Converging Lens
only occurs if object is outside of the focal length
Converging Scenario:
If object beyond R...
image forms between R and f.
Converging Scenario: If object at R...
image will form at R.
Converging Scenario:
If object between R and f...
image will form beyond R.
Converging Scenario: If object at f...
no image.
Converging Scenario: If object within f...
image is larger, upright, virtual.
Ultimate Formula
i = (o x f) / (o - f)
TBR Ex 10.9a An object is moved from w/n the focal length of a converging lens to a distance beyond the focal length. Image of the object is observed to change from:
UV to IR.
For a single lens or mirror, upright images are always ___ and inverted images are always ___.
Virtual & Real
3 Common Lens Aberrations
Spherical, Astigmatic, Chromatic
