Isnt frequency of light osscilation proportional to the Relative velocity of light with motion velocity of the ssource?
f =fo (Vs/Vr) where Vr is relative velocity of light?cn this be explained?

So where is speed of light measured relative to what point?

The speed of light is relative to the medium. It slows in different mediums. It is usually measured in a vacuum, but since a perfect vacuum does not exist, hmm.... what a pessimist I am.

The speed of light is constant relative to the observer. If you are moving away from the Sun at half the speed of light, light produced on your ship and the light from the Sun will both appear to move at the same speed. Assuming you make your measurements in vacuum, that speed will be the universal constant, c. The difference is that the light from the Sun will appear shifted towards the red, because your relative motion makes your space-time different from the Sun's. An observer at rest relative to the Sun will see your light as similarly red-shifted.
So yes, there is no absolute reference frame.

There is no general reference frame period. This has nothing to do with the speed of light. The principle is often known as the Galilean principle of relativity, and was known to both Galileo and Newton.
The observation that the speed of light is the same in all reference frames is a separate one, and leads to special relativity.

before each little thing, gravity would not ensue at gentle %. it really is instant. 2d, as you mind-set it, your mass would improve exponentially. So, to flow from ninety 9% to ninety 9.9% will require 10 situations extra power, no a lot less. and each 9 you upload after the decimal will require yet another 10 situations extra power. third, the exterior will be dashing in the direction of you in a large blur, heavily blue-shifted so the glaring wavelengths/frequencies will be between x-rays and gamma rays (for seen gentle). Fourth, when you're ejecting photons, that haven't any mass, out of a rocket, how can they reason the rocket, which has mass, to achieve their (gentle) %. this is scary what takes position once you've too little information.

SPEED OF LIGHT RELATIVE TO ANY OBSERVER OR IN ANY REFERENCE FRAME WHETHER IT MAY BE SOURCE OR ANYTHING.. ITS A CONSTANT
after ur add. details
i think ur confused of the dopler effect equation
in doppler effect frequency SHIFT is proportionlal to THE VELOCITY OF THE SOURCE relative to the observer and NOT LIGHT
the speed of light in doppler effect is constant and there is no term as "relative velocity"
AGAIN..
Speed of light can be measured from any frame of reference
and in any frame of reference its a constant

speed of light is not related to it's source.
