I'm having difficulty understanding how to estimate the location of an image in a lens/mirror.
I tried understanding it by going off the books question/answer section:
"A spherical concave lens has a focal length of 16 cm, and an object is placed 8 cm from the lens." It says the answer is 6.0 cm.
What formula is being used, I cannot figure out how they got 6 cm? All I see in the book for formulas is f=R/2 and R=2f.
I'm confused :(
