प्रश्न
Draw a ray diagram to show the appearance of a stick partially immersed in water. Explain your answer.
उत्तर
A stick partially immersed in water in a glass container appears bent or raised, as shown in the figure above. This happens because the rays appear to come from P' (which is the virtual image of the stick's tip P) due to refraction from the denser medium (water) to the rarer medium (air) at the surface, separating the two media.
