A converging lens with a focal length of 30cm and a diverging lens with a focal length of -64cm are 139cm apart. A 4.0cm tall object is 50cm in front of the converging lens.
distance between image and diverging lens has been calculated to be -32cm, and it is right.
M = -(s'/s) = (hi/ho)
The Attempt at a Solution
-(-32cm/50cm) = (hi/4.0cm)
hi = 2.56cm
I already got the mastering physics problem wrong. Used all my guesses. But the answer is 3.0cm and I have no clue how?
