Question

in air light velocity is 3×10^8 then what will be light velocity that refraction index is 1.5

Answer 1

Refractive index of a medium = Speed of light in vacuum/Speed of light in a medium. 1.5 = 3 x 108 / Speed of light in medium. Speed of light in the medium = 3 x 108 /1.5. = 2 x 108 m/s.
