Question

Find the speed of light in a transparent medium if the refractive index of the medium is 1.5​

Answer 1

Refractive index = Speed of light in vaccum / Speed of light in medium n = c / v

v = c / n = ( 3 x 10 ^ 8 m / s ) / 1.8 = 1.67 × 10 ^ 8 m / s

Speed of light in given transparent medium is 1.67 × 10 ^ 8 m / s
