Will there be a change in bending of pencil kept in gladd of water when it is obsreved from outside to thst of a glass of kerosene
Answers
Answer: Yes, there will be a change in the bending of the pencil kept in a glass of water when it is observed from outside to that of a glass of kerosene.
Explanation: Let us revise a small concept of refraction of light - Apparent Bending of an object ( pencil ) under the water.
An object ( in this case a pencil ) appears to be raised and therefore bent on the surface of water( or any other medium optically denser than air) due to the scientific phenomenon of refraction of light.
Now, the greater is the refractive index of the medium, the more bent the object will appear to our eyes.
We know that kerosene is optically denser than water so it has a greater refractive index than that of water,
Hence we can conclude that when viewed from outside the pencil will appear more bent and raised on the surface of the kerosene than on the surface of water.
