Achild’s toy sits on the bottom of a swimming pool in which the water depth is d=1.8 m. to a child standing at the pool edge, the toy appears to be a horizontal distance of 4.2 m away from the sidewall. assume the child’s eyes are 3.5m above the bottom of the pool. what is the actual horizontal distance from the sidewall to the toy?

Horizontal distance is 1.28 + 2.04 = 3.32 m

Explanation:

Given data:

from  below figure

Applying Pythagoras theorem

from Snell's law

solving for x we have

x = 1.28

Horizontal distance is 1.28 + 2.04 = 3.32 m
