WebThe changing of a light ray’s direction when it passes through variations in matter is called refraction. The speed of light in vacuum c = 2.9972458 × 10 8 m/s ≈ 3.00 × 10 8 m/s. Index of refraction , where v is the speed of light in the material, c is the speed of light in vacuum, and n is the index of refraction.
