Question

A grizzly bear is sitting on a rock in the middle of a calmriver when she observes a fish directly below. If the apparentdepth of the fish is 0.60 m, what is the actual depth at which thefish is swimming? The index of refraction of water is 1.33.

a. 0.71 m
b. 0.45 m
c. 0.80 m
d. 0.62 m
e. 0.53 m A grizzly bear is sitting on a rock in the middle of a calmriver when she observes a fish directly below. If the apparentdepth of the fish is 0.60 m, what is the actual depth at which thefish is swimming? The index of refraction of water is 1.33. 0.71 m 0.45 m 0.80 m 0.62 m 0.53 m

Explanation / Answer

   when the observer is directly above thesubmerged objact the apparent depth d' and the actual depth dare related by    d' = d (n2 / n1)    n1 is tthe index of refraction ofthe medium where the observer exists and    n2 is tthe index of refraction ofthe medium where the object exists    solve for d'    d' = ........ m
