I'm not sure what you mean by that, sorry... I talked to another student and they said that when you use the lens-makers equation, if it's a converging lens then you do ##1/f=(n-1)(1/R_1+1/R_2)## Looks like that was my problem.

Do you mean set D equal to R1 and R2? If I do that, then (1/R1-1/R2) comes out to be 0. Then the focal length is basically infinity.

Find the resolving power of a microscope lens in terms of its diameter Homework Statement In this problem, we will find the ultimate resolving power of a microscope. First of all, in order to obtain a large magnification, we want an objective lens with a very short focal length. Second, in...

Homework Statement A nonuniform bar 4 meters long has a weight of 70 Newtons. The bar is on a fixed pivot at its center of mass which is 1 meter from the heavy end. If a 300 Newton weight is placed 0.4 meters left of the center of mass and a 100 Newton weight is placed 1.0 meters right of the...
