Aperson is lying on a diving board 3.50 m above the surface of the water in a swimming pool. she looks at a penny that is on the bottom of the pool directly below her. to her, the penny appears to be a distance of 5.00 m from her.

1.995 m

Explanation:

Distance of penny as seen by the person = 5 m

Height of person from water surface = 3.50 m

Apparent depth of penny = 5 - 3.50 = 1.5 m

refractive index of water, n = 1.33

real depth / apparent depth = n

real depth = 1.33 x 1.5 = 1.995 m

Thus, the actual depth of water at that point is 1.995 m.
