Echo, a dolphin is trying to jump through a circular hole in his enclosure to escape from the aquarium.
From echo's perspective just under the water surface, does the whole seem easier or harder to fit through ? and does it seem higher or lower ?
refractive index of water = nWater =1.33
refractive index of air = nAir =1.00
a) the whole looks harder to fit through than it actually will be
b) the whole looks easier to fit through than it actually will be
c) the hole looks higher than it actually is
d) the whole looks lower than it actually is
