Question

why does stick immused in water appears bent and small in size ? explain with suitable ray diagram ?​

Answer 1

Answer:

this is because of refraction of light.

A stick appears bent because of apparent depth

apparent depth is actually not the real depth but is the result of refraction of light . Because of which the observer sees the stick bent instead of standing straight. Moreover the stick bends inwards beacuse the air is a rarer medium than water so the stick appears to bend towards normal
