does speed of light varies, if you throw it from moving car?

Answer 1

No, the speed of light is the same whether it is coming out of a stationary torch or a moving torch!!

This was one of the deepest realisation that Einstein made and which became one of the postulates of Special Theory of Relativity.

As a matter of fact, this particular question was in Einstein's mind since he was a 10-11 year old child. Here is the question he asked himself: If I hold a mirror in front of me, and I move at the speed of light, will I be able to see myself? Questions like this, in addition to experiments failing to detect presence of ether as a medium used for light to travel finally resulted in his formulation of the special theory of relativity.

Answer 2

No, the speed of light is constant no matter where you measure it, on the ground, in a moving car, on arocketship, on another beam of light (if you could ride on top of a beam and light and then turn on a flashlight). Even if you have two spaceships moving toward each other, and both ships are traveling at 99% of the speed of light, and if a light beam were turn on on one ship and aimed at the other, we will still see the beam of light traveling at the exact same speed, 300,000 km/sec.

This is a very non-intuitive result, but it is a true fact. However, because the speed of light is constant, then what is NOT constant is then the "speed of the flow of time", which will depend on the speed of the observer. This is what they mean when they say that time is relative, and that time slows down for fast moving objects.

Answer 3

The speed of light remains the same no matter how fast its source (a moving car for example) is going. Fire a bullet from a moving car and the speed of the bullet will have the speed of the car added to it, but light just doesn't work that way.

Answer 4

hey that's a good question ,when u throw a light froma car it really changes it's speed ,but it will be not observed by the human's ,
when u throw a light it's medium of travelling changes it's medium in car is different and when the light is out of the car it's changes so the speed of light is affect by the new medium.
let us consider an example whe you pass a light in a bucket u observe that the light is slightly bent that easily clear's your doubt, ok
keep asking question'sbyeeeeeeeeeee

Answer 5

If the car is stagnant, then speed of light is maintained
If the car is accelerating, then the speed of light is reducing but negligible.
If the car is decelerating, then the speed of light is increasing but negligible
If the car is maintaining at the speed, then the speed of light is maintained.
It is just the simple Relative Law.

Answer 6

According to theory of relativity speed of light is constant and does not vary in any condition.Light can travel in any medium at certain constant speed is discovered by Einstein.because it is not made of particle

Answer 7

no for a given medium the speed of light always remain constant, this is the basic premise of relativity. the speed of light varies only in different mediums thus the speed of light is different in glass as compared to vaccum. when light traverses from one medium to other its speed keeps on varying accordingly thus when it enters vaccum from say glass it will resume its speed corresponding to vaccum

Answer 8

The speed of light is the same in all directions according to einstein's special theory of relativity

Answer 9

No. That is the essential point of relativity: the speed of light is constant in any inertial frame.

Answer 10

ya, it does.
but with respect to a moving observer like u only. for a stationary reference, it is constant. however wrt u also the variation is negligible 'coz ur car is moving tooo much slowly compared to light.
and never say "we throw light". say we direct light beam or we flash a light beam.
