- Homework Statement
- Suppose that you focus a camera directly down on a letter printed on this page.
The letter is then covered with a 2.00-mm thick microscope slide (n = 1:55). By
how much must the camera be raised in order to keep the letter in focus?
- Relevant Equations
- Snell's law or refraction at a spherical interface?
I'm really stuck on this and have no solution only a numerical answer! Any pointers in the right direction would be really appreciated!
