    To get the speed of light in this class glass, used the following equation

    v = c/n; where c is the speed of light in a vacuum and n where the index of refraction

    Based on my research the index of refraction of the class glass is 1.59

    Given

    c = 3.00 x 10^8 m/s

    n = 1.59

    Solution

    we will use 3.00 for c to get the speed of light in class glass cause 10^8 m/s is fixed

    v = 3.00 / 1.59

    v = 1.886

    So the speed of light in this class glass is 1.89 x 10^8 m/s
