Vedclass · Answer

(B) The absolute refractive index of a medium is defined as the ratio of the speed of light in a vacuum $(c)$ to the speed of light in that medium $(v)$.Mathematically,$n = c/v$.For water,the speed of light is approximately $2.25 	imes 10^8 	ext{ m/s}$,and the speed of light in a vacuum is $3 	imes 10^8 	ext{ m/s}$.Therefore,the refractive index of water $n = (3 	imes 10^8) / (2.25 	imes 10^8) = 3 / 2.25 = 300 / 225 = 4/3 \approx 1.33$.
