Question

You are given kerosene, turpentine and water. In which of these does light travel fastest? Justify your choice.

Answer 1

in water bcz the density of water is less

Answer 2

Explanation:

given kerosine =1.44, turpentine =1.47 ,water=1.33

lights travel the fastest in a medium Having minimum optical density of lower refractive index

since,

water=1 .33 is the lowest speed of a light is maximum in water
