Let's speed of light in vacuum = c
Refractive index= c / 2/3 × c
Refractive index = 3/2 = 1.5
Refractive index= c / 2/3 × c
Refractive index = 3/2 = 1.5

Given :
The speed of light in a given medium is 2/3rd of its speed in vacuum
To Find :
The absolute refractive index of the medium
Solution :
Velocity of light in vacuum (c) = 3 × m/sec
As per question,
Velocity of in a given medium (v) = × velocity of light in vacuum
= × 3 ×
= 2 × m/sec
Absolute refractive index (μ) =
=
= 1.5
Therefore, the absolute refractive index of the medium is found to be 1.5.
