WebThe speed of light, which scientists have thoroughly examined, is now expressed as a constant value denoted in equations by the symbol c. Not truly a constant, but rather the maximum speed in a vacuum, the speed of light in km, which is almost 300,000 kilometers per second, can be manipulated by changing media or with quantum interference. WebMathematically, light travels at the speed of 300000000 meters per second in vacuum. It is a constant quantity which remains the same throughout the reaches of humans. This constant attribute, though changes when the medium changes. In vacuum, there is no obstacle for the light waves and hence, it travels unobstructed.
