EDIT:
Concave mirror
O before C: Real, after Virtual
Converging lens
O Before f, real, after virtual
Convex mirror ---> virtual always
Concave lens ---> virtual always
Plane: Virtual always
Is this right?
Also 1/o + 1/i = 1/f= 2/r
So how do I judge magnification? m=-i/o, one of my books said to take the absolute value.... so if I get -6 is that 6x magnification so 6x larger? Is there any pattern like virtual images are smaller etc?
