Question

The velocity of light in kerosene is 2.08×10-8 ms-1, calculate the refraction index of kerosene

Answer 1

Answer:

1.44

Explanation:

We know,

Refractive index of the medium=

                      Speed of light in the medium /Speed of light in air

Hence,  

Refractive index of the kerosene=

                      Speed of light in the kerosene /Speed of light in air

                       

                         = (2.08*10^8) / (3*10^8)

                         = 1.44
