 P: 56 http://physicsforums.com/archive/index.php/t-77612.html here's a link to the same question which has already been inquired before by someone else. according to the question, it asks to calculate the "actual" depth and once I have read all the replies on that page, the author seemed to calculate the answer. I've tried it myself and acquired the same answer. However, I'm a little confused with the given unit "1.0m" in the question. Is it just there to confuse the reader? because it has not been included in any of the calculations. Sorry for posting too many questions :( and thank you in advance.

oh what I meant was,
was that 1.0m necessary for calculating the final answer?

## Apparent & Actual Depth

Ah... Are you referring to the statement: "She estimates that her eyes are about 1.0m above the water's surface"?

If so, then no, that fact seems irrelevant to the problem.
 P: 56 I'm very sorry to hold u up Doc, I've been trying to figure out a diagram for that question, would you be able to take a look? Thank you very much and sorry T_T
 Mentor P: 40,276 Your diagram looks good to me.
