Think about three identical rays of light in air that are refracted upon entering in three different materials, each with a different speed of light. Calling “c” the speed of light in vacuum, where for example 0.50c means 50% of the speed of light in vacuum.  Material A is  Diamond where the speed of light is 0.41c Material B is Amber, where the speed of light is 0.65c Material C is Water, where the speed of light is 0.75c Rank the materials according to how much the light ray bends toward the normal, from the ray most away from the normal to the ray closest to the normal.
