The absolute index of refraction of material X is 166. The speed of light in air is generally accepted to be 186000 miles per second. Refractive index of the water is 133 and for glycerin is 1473.
N speed of light in a vacuum speed of light in a medium The index of refraction of the medium is the ratio of the two.
Your IR of Glycerin is stated as 146. Calculate the angle of refraction of the light ray as it enters the corn oil from air. Physics students learn the speed of light c is the same for all inertial observers but no one has ever actually measured it in one direction. Determine the speed of this ray of light in material X.
