Homework Statement
A transparent photographic slide is placed in front of a converging lens with a focal length of 2.44 cm. The lens forms an image of the slide 13.2 cm from the slide.How far is the lens from the slide if the image is virtual?
nearer possible distance =
Homework Equations
1/p + 1/q = 1/f
The Attempt at a Solution
I was able to find the distance of the lens from the slide if the image was real by 1/x + 1/(13.2-x) +(1/2.44) and solving for x.
However I assume that since the object is virtual the image is between the slide and lens. So, P= 13.2 + x and q=-x while f=2.44. When I plug this into the thin lens equation the solution is wrong
How is The attempt wrong
