Vedclass · Answer

(B) The refractive index $(n)$ of a medium is defined as the ratio of the speed of light in a vacuum $(c)$ to the speed of light in the medium $(v)$: $n = c / v$.Given that the refractive index $n = 1.5 = 3/2$.We need to find the ratio of the velocity of light in the medium $(v)$ to the velocity of light in a vacuum $(c)$,which is $v / c$.From the formula $n = c / v$,we have $v / c = 1 / n$.Substituting the value of $n$: $v / c = 1 / (3/2) = 2/3$.Therefore,the velocity of light in the medium is $2/3$ times the velocity of light in a vacuum.

What is the ratio of the velocity of light in a transparent medium with a refractive index of $1.5$ to the velocity of light in a vacuum?
