WebThe speed of light depends upon the medium through which it travels.The speed of anything with mass is always less than the speed of light in a vacuum. other characteristics The amplitude of a light wave is related to its intensity. Intensity is the absolute measure of a light wave's power density. 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.
