Properties of Images

When the focal length is positive, the lens is converging. When the focal length is negative, the lens in diverging.

When stating the properties of an image there are generally four. Images are classified by their position, kind, attitude, and magnification.

Don't forget to draw your three lines when drawing a diagram!

Converging:

Distant: The image is behind the lens and at F. The image is real as well as inverted and smaller than the object.

Outside F`: The image is behind F and real. It is also the same size and flipped.

At F`: When there is an object at the focal length of a converging lens there is never an image.

Between F` and O: A virtual image that is in front of F will occur. The image is also larger then the object and upright.

Diverging:

Distant: The image is positioned in front of the lens at F. The image is also virtual as well as smaller than the original object. It remains upright when the light hits the lens.

Outside F, At F, Between F and O: The image is smaller, virtual, upright, and between F and O.
