### 1 Concepts and Principles

An image can be formed by refraction from a planar surface. The object and image distances for refraction from such a surface are related by

\begin{gather*} s'=-\dfrac{n_2}{n_1}s\tag{*} \end{gather*}

s ′ =− n 1 n 2 s (*)

The minus sign tells us that we have a virtual image.

n_1 n 1

is the index of refraction of the medium of the object,

n_2 n 2

is the index of refraction of the medium of the observer, distance

s

s is called the object distance, and

s' s ′

the image distance, where

s s and s' s ′

are measured from the boundary.

What do you know about apparent depth? The diver's head is at an apparent depth and so are her feet. The difference between apparent depths is the diver's apparent height.

So after reading my book I found something that talks about a diver. The problem is it talks about finding the diameter of the circle of which you can see in the water. D= 2h tan theta c. Theta c= sin^-1 (1.00/1.33) for the water air boundary and h is the depth of water. This is all I can find even close to the problem in the book. In the problem however we are not given any information about the angle just that he is right above. If he is at at 90 degree angle I don't see how he can tell a height at all. He would just see his head. I don't have any information about the depth of the water or the apparent depth of the diver. So I am really frustrated with this problem.

Try doing some research on the web on "apparent depth". Here is an example of what you might find

THANK YOU SO MUCH. I seriously have tried everything! I am really confused on why my book does not have the formula in it. But thank you again.
