    Answer:

    1.2

    Explanation:

    Data obtained from the question include:

    Velocity of light in the oil (V) = 2.5×10^8m/s

    Velocity of light in air (C) = 3×10^8m/s

    Refractive Index (n) =.?

    The rafractive index (n) for the oil is given by:

    Rafractive index (n) = Velocity in air (V) /velocity in oil (V)

    n = C/V

    n = 3×10^8 / 2.5×10^8

    n = 1.2

    Therefore, the Refractive Index of the oil is 1.2.
