I am stuck on this problem because it been like 6 yrs since i took geometry and its due by 9 am. please help!
Derive the thin lens equation:
1/object distance + 1/ image distance = 1/focal length
for a divergent lens, using a diagram of a divergent lens (hint: use similar triangles)
I have no idea where or how to start. please show me how to do it. I know the focal length for a diverging lens is always negative and always produces a virtual image.
