    Part (a) should be convex.
    Part (b)You have to put the height of your image over the height of your object, like a ratio. Once you do that, multiply that answer by the "20cm." Your answer should be a negative.
    Part (c) Use the equation: 1/do+1/di=1/f
    Part (d) Multiply the answer you got for part (c) by two
