WebThe refractive index of the medium can be calculated using the formula: n = c/v. Substituting the values in the equation, we get. n = 3 × 10 8 m/s/1.5 × 10 8 m/s = 2. The refractive index of the medium is 2. The speed of light in an unknown medium is 1.76 × 10 8 m/s. Calculate the refractive index of the medium.
