Answer:The refractive index of glycerine = 1.46. the speed of light in glycerine is 2.05 into 10 to the power 8 metre per second . Refractive index= Speed of light in air /Speed of light in glycerine. 1.46= speed of light in air /2.05x10^8m/s. speed of light in air = 1.46× 2.05×10^8m/s = 2.99×10^8m/s . its nearly equal to =3x10^8 m/s.
