Given: n (refractive index of the specified medium) = 2; C (speed of light) = 3 * 10 ^ 8 m / s.
To determine the value of the speed of light in a certain medium, we will use the formula: n = C / Vav, whence we express: Vav = C / n = 3 * 10 ^ 8/2 = 1.5 * 10 ^ 8 m / s.
Answer: The speed of light in a certain medium, according to the calculation, is equal to 1.5 * 10 ^ 8 m / s.
