Why Does Light Travel Faster Than Sound
The speed of light in a vacuum is constant and always has been. It is the ultimate speed limit in the universe. It travels at a whopping 186,000 miles per second. But what about sound? It travels much more slowly, at about 1,100 feet per second. Why is that? It has to do with the…

Light and sound waves are both forms of energy that travel through the air or other mediums. They are both created by vibrations. Light waves are created by the vibrating of electrons in an object. The faster the electrons vibrate, the more energy the light wave has. This is why light waves from a light…

The speed of sound in space is not constant. It depends on the density of the material it is travelling through. In a vacuum, the speed of sound is the speed of light. However, in a medium such as air, the speed of sound is slower than the speed of light. The speed of sound…
