Question

Explain why,a stick half immersed in water appears to be bent at the surface?​

Answer 1

Explanation:

A stick or a pencil half immersed in water at an angle appears bent due to refraction of light at the air-water surface. The two refracted ray CX and DY, when produced backward, appear to meet at point I, nearer to the water surface than O. Similarly each part of the immersed portion of the stick raised.

Answer 2

Answer:

This is due to the refraction.

The apparent bending of the stick is due to the refraction of light when it passes from water into air. A ray of light OC coming from O passes from water into air and gets refracted away from normal (along CX). Another ray OD gets refracted along DY. The two refracted rays CX and DY, when produced backwards, appear to meet at point I. Thus, I is the virtual image of the end O of the stick. So, the stick appears to be bent as shown below.
