BR Optics question

[Natnow]

Hi all,

I have a question I need help with answering:
When an object is moved from within the focal length of a diverging lens to a distance beyond the focal length, the image is observed to:
A. change from upright to inverted, and move away from the lens
B change from inverted to upright and move closer to the lens
C remain upright and move away from the lens
D. remain inverted and move closer to the lens

Thank you!

If you're good at drawing, you can see pretty easily what's going on. The image will remain upright, but will move away from the lens.

Here's an image of that --> http://www.acs.psu.edu/drussell/Demos/RayTrace/Lenses.html

If you're quick at doing math, you could figure out the answer that way.

Inside focal length, f=-10 and do=5:
1/f = 1/di + 1/do
1/(-10) = 1/di + 1/(5)
di = -3.33

Outside focal length, f=-10 and do=15:
1/f = 1/di + 1/do
1/(-10) = 1/di + 1/(15)
di = -6

Hope this helps!
