Question 2 states: A camera uses a converging lens with a focal length f = X to focus light on a flat, light-sensitive material (screen). The camera is perfectly focused on an object at a distance 5X. 15) 2) What is the image vergence in terms of X? 3) To two decimal places, what is the magnification of the lens in question 15? Solution Object vergence = 1/5X = 0.2/X. Image vergence = 4/5X = 0.8/X. Magnification = 0.25 The image formed is virtual, upright and reduced..

1. Question 2 states: A camera uses a converging lens with a focal length f = X to focus light on a
flat, light-sensitive material (screen). The camera is perfectly focused on an object at a distance
5X.
15)
2) What is the image vergence in terms of X?
3) To two decimal places, what is the magnification of the lens in question 15?
Solution
Object vergence = 1/5X = 0.2/X. Image vergence = 4/5X = 0.8/X. Magnification = 0.25 The
image formed is virtual, upright and reduced.
