Physics Question on Refraction of Light
To a fish under water, viewing obliquely a fisherman standing on the bank of a lake, the man looks
A
taller than what he actually is
B
shorter that what he actually is
C
the same height as he actually is
D
depends on the obliquity
Answer
taller than what he actually is
Explanation
Solution
When a ray from man O in air (rarer medium) goes to water (denser medium), then it bends towards the normal. Extend MN backwards meet at point O′. Therefore, it appears' to the fish as if the man is taller than what he actually is.
