# Real Object, Images formed by a single converging or diverging lens

#### skibum143

1. Homework Statement
Starting with a real object, which of the following statements are TRUE about the image formed by a single lens? (Choose ALL correct answers, e.g. B, AC, CDF.)

A) For a converging lens an object has to be placed between the focal length and the lens in order to form a virtual image.
B) A diverging lens can produce a real, inverted, reduced image.
C) A converging lens can produce a virtual, upright, enlarged image.
D) A converging lens cannot produce a real, inverted reduced image.
E) A converging lens can never produce a virtual, upright, reduced image.
F) A diverging lens always produces a virtual, upright, reduced image.

2. Homework Equations
laws of rays passing through a lens

3. The Attempt at a Solution
I keep getting this wrong, and I'm not sure which one I've mixed up.
A) True - I believe this is the only way to get a virtual image for a converging lens
B) False - Diverging lenses CANT produce real images
C) True - if the object is between the focal point and the lens
D) False - this is possible if the object is placed, say, 2 times the focal length away from the lens
E) True - this is not possible because any virtual images are enlarged ???
F) False - diverging lenses can produce inverted images as well

can someone help me figure out where I'm wrong?
These are the answers I've tried:
TFTFTF
TTTFTF
TFTFTT
TFTFFF

I believe the last one is true. It seems like any raytrace on a diverging lens forms a upright reduced and virtual image.

#### skibum143

I guess my prof said that a diverging lens could possibly form an inverted image, although I'm not sure how.

I also already tried that combination: TFTFTT
So I must either have another one wrong or something.... not sure...

I find that hard to believe as all virtual images are upright.

#### skibum143

I didn't know that all virtual images are upright, that is good to know!

However, if Part F is true, I still have something else wrong, as I tried: TFTFTT

So I'm not sure what other one I have wrong...

#### AtticusFinch

Yeah I'm not sure what else could be different TFTFTT seems right to me.
