Answer 1

Answer:

"When we observe a fish aquarium from the bottom of it, the size of the fishes will be larger than its "original size". This is because of the optic phenomenon called as refraction. ... Here in the fish tank, the light rays travel from rarer medium to denser medium. So, the fishes appear in a larger size.
