Converging lens questions
Can someone please help me answer these questions
A converging lens produces an image twice the original. All answers must be given in mm to the nearest mm
1. If object is placed 1.1m in front of lens, calculate image distance? I converted 1.1m to mm which is 1100mm and then I did 1100×2 which is 2200 mm is this correct
2. Focal length of the lens
I got 735mm but not entirely sure on this

use 1/u + 1/v = 1/f to get a value for f. u is negative btw
