1) Concave/Convex Lens
A) 12 cm to the left of convex lens of focal length 8.2 cm
- distance from the convex lens, i = [(1/f)-(1/o)]-1 = [(1/8.2)-(1/12)]-1 = 25.89 cm
- Is the initial image Real or Virtual? Real
- Is the initial image Enlarged or Diminished? Enlarged
- Is the initial image Upright or Inverted?
- What is the initial magnification? m? m=-i/o = -25.89/12 = -2.1575
- Draw a 3 ray diagram for this. (need help with this if possible)
B) a diverging lens of focal length -9cm is placed 20 cm to the right of the convex lens. Find: (need help with this whole section)
- Distance from the concave lens, i
- Is the final image Real or Virtual?
- Is the final image Enlarged or Diminished?
- Is the final image Upright or Inverted?
- What is the Total Magnification? M?
