examine the second figure(figure 2), in which you see jackie's spaceship traveling at 1000 km/hr , with the ship's headlight on. according to special relativity, jackie would say that a beam of light from the headlight is traveling at , and you would say that the beam of light is traveling at .

Sagot :

light from the headlight is traveling at speed of light , and you would say that the beam of light is traveling at Speed of light.

A fundamental premise of relativity is that everyone always measures the same speed of light, c, no matter how the observer or the light source may be moving. Note that this makes light different from material objects such as baseballs.

The speed of light in a vacuum, commonly denoted by c, is a universal physical constant important in many areas of physics. The speed of light, c, is exactly 299,792,458 meters/second (about 300,000 km/second; 186,000 miles/second; 671 million miles/hour). According to special relativity, c is the speed at which conventional matter or energy (and thus any signal carrying information) can travel in space.

All forms of electromagnetic radiation, including visible light, travel at the speed of light. For many practical purposes, light and other electromagnetic waves appear to travel instantaneously, but for long distances and highly sensitive measurements, finite velocities have significant implications.
