Assume a car is travelling at the speed of light And the driver turns an its head lights and rear lights,What happens to that light?????????? Please Give a satisfactory answer with detail.(10 points)
Time for the driver slows down as he/she approaches the speed of light. So if he was moving at 99.99999999% of the speed of light then his journey would be nigh instantaneous, giving him no time to turn on the lights. If his trip was very long then he would see the light ahead of him no problem but to an onlooker the light would only be a fraction ahead of the car for a very long time.
look up relativistic equations and plug in the numbers yourself. you will find that the head beams of light are traveling at speed of light, not twice the speed of light. the rear beam is not going anywhere. this is relative to stationary observer. for the driver, the head light is not functioning and the tail lights are going speed of light.
We don't know. Never been able to test it. Theory would say that the light from the beams would be traveling 2x the speed of light from a stationary position. Dumb it down a little bit. If an object is traveling 1m/s and you are walking 1m/s in the same direction, wouldn't you be traveling 2m/s from static? The interesting question is what happens if a car is moving at light speed and shines a light backwards, what happens to that light? Is it stationary? PS - Guy above has no imagination
According to the well tested theory of Special Relativity, the speed of light is the only absolute speed in the universe. That means that whoever measured its speed, no matter what THEIR speed is, they will still measure the speed of light at about 186,000 miles a second. So if you COULD travel at the speed of light - lets say you travel just a bit slower - your headlights would shine forward at 186,000 miles a second, just like you have always experienced on Earth, just like they always do. and your taillights would shine backwards at the speed of light. And someone on earth would see your front lights shining forwards at the speed of light, and your back lights shining backwards at the speed of light. This is not a simple idea, and it is not some illusion or trick of perspective. But it does appear that our universe is that way.
To anyone in the car, the lights would be shining out, just as they would in a slower moving car. To an outside observer, they would still see the lights, but they would show as different colours, due to the Doppler affect.
