Question

The top of a swimming pool is at ground level. If the pool is 1.83 m deep, how far below ground level does the bottom of the pool appear to be located for the following conditions?
(a) The pool is completely filled with water.


1.38 m below ground level

(b) The pool is filled halfway with water.

1.688m below ground level
THIS IS WRONG!
Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error.

Explanation / Answer

a)n = real depth/apparent depth

=>4/3 = 1.83/apparent depth

=>apparent depth = (3*1.83)/4 = 1.3725m

b)If the pool is filled halfway with the water,

Then n = real depth/apparent depth

=>4/3 = 1.83/2apparent depth

=>apparent depth = 0.68625

Required apparent depth = apparent depth + (1.83/2) = 1.60125m
