Light
What is light? It is electromagnetic radiation with a certain portion of the electromagnetic radiation. The speed of light is very different in different environments. For example, the average speed of light in the air is 300,000,000 meters per microsecond. That is extremely fast. The speed of light is faster than the speed of sound, so that is why when you see fireworks or lightning, you see the light first, and then a couple seconds later you hear the sound. In water, the speed is 250,000,000 meters per microsecond. The reason that diamonds reflect light so well is because the light goes through them faster than it leaves them, so inside the diamond the speed is about 72,000,000 meters per microsecond, and so some of the light stays in the diamond.
