Notes:

• all of the objects in this diagram are real.

• For mirror, real images are formed on the same side as the object

• For lenses, real images are formed on the opposite side as the object

Diverging Systems (concave lens/ convex mirror)

Notes:

• all of the objects in this diagram are real.

• For mirror, real images are formed on the same side as the object

• For lenses, real images are formed on the opposite side as the object
