WebJan 9, 2024 · The speed of light in a vacuum is defined to be 299,792,458 meters per second. The value is defined because the meter is defined based on the speed of light. Light is energy rather than matter, but it does exert pressure and it has momentum. Light bent by a medium is refracted. If it bounces off a surface, it is reflected. WebWhen a wave or light ray moves from one medium to another its speed changes. The direction of the ray may also change. This property of waves is called refraction and commonly occurs with...
