Question

a pencil when dipped in water in a glass tumbler appears to be done at interface of air and water will the pencil appear to be bent at the same extend if instead of water we use liquid like kerosene or turpentine support your answer with reason​

Answer 1

the pencil bends due to refraction

the refractive index of air is 1.0003

and water 1.33

whereas the kersine make has 1.39 and tiupetine oil has 1.47

hence the refractive index is more so the refraction is also more and so it will more BEND towards normal

IN EASY WORD THE PENCIL WILL BEND MORE

Answer 2

Answer :

The refracted image of pencil will bent more as the water is having the refractive index lesser than the kerosene.

The pencil's image will appear more upward to the tumbler i.e, the image if the pencil will move more away from the normal.

I hope my answer is helpful to you. If it is don't forget to mark it as brainliest answer...
