explain speed of light

The speed of light is a constant and fundamental physical property of the universe. It is the highest speed that anything can travel in a vacuum. It is the speed at which light travels in a vacuum, and is equal to 299,792,458 meters per second (approximately 186,282 miles per second). To put it into perspective, light can travel around the world almost 7.5 times in one second, and it could go from the Earth to the Moon in less than one and a half seconds! An analogy that can be used to explain the speed of light is that it is like a runner sprinting on a track. The runner is the light, and the track is the vacuum. As the runner sprints, they eventually reach a certain speed, and they just can’t go any faster, no matter how hard they try. The same is true with light, as it travels in a vacuum, it eventually reaches a certain speed, and it can’t go any faster. A fun fact about the speed of light is that it is the same for everyone. It does not matter how fast or slow you are moving, the speed of light will remain the same.
