Question

The speed of light is vacuum is 3.0 ×108 m/s. If the refractive index of a transparent liquid is 4/3, then find the speed of light in the liquid?​

Answer 1

Answer:

Speed of light in liquid = 2.25 x 10⁸ m/s

Explanation:

R.I of medium  $n_{m}$ = $\frac{speed of light in air or vacuum}{speed of light in medium}$ = $\frac{c}{v}$

                         ∴ v = c/$n_{m}$ = 3 x 10⁸ /(4/3)

                                           = 9/4 x 10⁸ m/s

                                           = 2.25 x 10⁸ m/s
