doesnt the doppler effect measure light relative to a source(a moving frame of reference)?As relative speedchanges wavelenght changes?

Isnt relative velocity of light relative to a source exist as C minus velocity of the sourceVr=C-v ?

i think yes , because light also have a mass, it is a arrey of photon particals,and second all thing in univerce is relative and rendum then why not light speed ? more thinking should be required on this.

The speed of light is a constant and is not relative to any inertial frame of reference.
If I am pointing a flashlight forward and I am traveling at the speed of light, that does not mean that the light traveling from the end of the flashlight is moving at twice the speed of light.
The speed of light is the same no matter where you are or what you're doing.

the speed of light is the same with respect to any frame of reference. That, is relativity. I don't understand it either.

Observational evidence exhibits that the speed of propogation of light by vacume is continually a similar realtive to any observer, inspite of his state of action. it truly is the critical tenant of the concept of relativity. the rationalization you won't be able to bypass swifter the mild stemms from the notorious E=MC2 (E- skill, M- mass, C- % of light) even as an merchandise is mooving it acquires kinetic skill. because, as you will see that from the eqation, skill and mass are inerchangable, so the item also acquires added mass. because the "replace fee" between mass is so large - small volume of mass for an infinite volume of skill, the end result isn't noticiable in customary velocities. notwithstanding, as you attitude the speed of light, the item will advance very much in mass with each upward thrust of the speed of that's action. Now, appart from the very reality it must be cruched by using garvitational forces, that's not conceivable for it to actual attain the speed of light because the more beneficial massive that's the more beneficial skill is nedded to make it bypass swifter, and if it does bypass swifter nonetheless more beneficial skill is necessary to make it bypass swifter nonetheless and so on. there is not adequate skill in the univese to make it actual bypass the speed of light. mild can holiday at this % because it has no mass.

Einstien once told that speed of light is constant irrespective of frame of reference but alas he never explained me why :(

yes it is relative to an absolute frame of reference,,,,,
just read law of relativity of free space

no such thing as an absolute frame of reference.....the beauty of light......for a given medium its speed is constant.....NO MATTER WHAT THE FRAME OF REFERENCE...the speed of light is 299 792458 m/sec

No, the speed is constant.
