Q. To a fish under water, viewing obliquely a fisherman standing on the bank of the lake, the man looks
A) Taller than what he actually is
B) Shorter that what he actual is
C) The same height as he actually is
D) Depends on the obliquity
Explanation
(b) When a ray from main $O$ in air (rarer medium) goes to water (denser medium), then it bends towards the normal. Extent$\ MN$ backwards meet at point$\ O''$. Therefore, it appears to the fish as if the man is taller than what he actually is
