Question

material medium-air,ice,water, kerosene,crown glass, benzene
refractive index-1.0003,1.31,1.33,1.44,1.52,1.50
Answer the following questions with the help of
the above table.
i) Find the speed of light in water.
In which medium light travels fast? Why?
iii) Find the relative refractive index of kerosene
with water.
iv) In which medium light travels slow? Why?
) Find the speed of light in Benzene.​

Answer 1

Answer:

1. Vwater=2.25*10^8m/s

2.light travel faster in air due to low refractive index

speed of light inversely proportional to refractive index

3. refractive index of kerosene with respect to water is 4.36

4. speed of light travels slow in in the medium which has highest refractive index that is n=1.52

5. speed of light in benzene=1.97*10^8m/s
