1. Lens diagram follow up
With calculations!!!

2. 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)

3. 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 = cm
di = 2.1 cm
f = 1.6 cm

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