Vedclass · Answer

(B) The refractive index $n$ is defined as the ratio of the speed of light in vacuum $c$ to the speed of light in the medium $v$,given by $n = \frac{c}{v}$.Since the speed $v$ is the distance $d$ traveled per unit time $t$,we have $v = \frac{d}{t}$.Substituting this into the refractive index formula: $n = \frac{c}{d/t} = \frac{ct}{d}$.Rearranging to solve for time $t$: $t = \frac{nd}{c}$.Given: $n = 1.5$,$d = 4 \ cm = 4 	imes 10^{-2} \ m$,and $c = 3 	imes 10^{8} \ m/s$.Substituting the values: $t = \frac{1.5 	imes 4 	imes 10^{-2}}{3 	imes 10^{8}}$.$t = \frac{6 	imes 10^{-2}}{3 	imes 10^{8}} = 2 	imes 10^{-10} \ s$.
