Hmm, I wonder Light doesn’t travel at the same speed in all materials. In a vacuum where there’s no air or matter light travels at its maximum speed, approximately two 99,792 kilometers per second. However, when light enters other materials like air, water, or glass, it slows down.
The refractive index is a number that tells us how much a material can bend light. The higher the refractive index, the more the light will bend. For instance, diamond has one of the highest refractive indices, which is why diamonds sparkle so brilliantly, they bend light in multiple directions.
