Lens diagram follow up With calculations!!!

What will the image look like if: (consider: inverted/upright, +/- magnification, same side of lens as object/opposite side lens as object) do < 1 f : Upright, +M, same side (so di is neg. sign)(virtual image) do = f: No image do > 1f but do < 2f Inverted, - M, opp. Side (+ di, - hi)

Numerical calculations time: If the height of an object is 5 cm, do = 7cm, and the M = - .3, then what is hi, di, and f =? Make a diagram of the described situation please. hi = - 1.5 cm di = 2.1 cm f = 1.6 cm

do = 7 di = 2.1 ho = 5 hi = -1.5 f = 1.6
