If the speed of light in a medium of absolute refractive index of 1.5 is 2×108m/s then the speed of light in vacuum is ____ ×108m/s.

If the speed of light in a medium of absolute refractive index of 1.5 is 2×108m/s then, the speed of light in vacuum 3 ×108m/s.Refractive index of a medium is defined as the ratio of speed of light in vacuum to the speed of light in the medium. i.e., Refractive index of a medium =Speed of light in vacuum Speed of light in medium⇒nb= cvBWhere nb is the refractive index of the medium, c is the speed of light in vacuum/air, and vb is the speed of light in the medium.Speed of light in vaccum, c= nbvB⇒c=1.5×2×108 m/s.⇒c=3×108m/s.
