Assumption: The object is moving forward. The light is emitting from the front of the object.

The speed of light is NOT constant. Light travels through our atmosphere at 2/3 its speed in a vacuum.

It travels even slower through glass. I teach fiber optics technology among other things.

Is the anser yes as today's, police, radar guns use lasers to detect speed?

The speed of light is always the same. It is RELATVISTIC to the medium.

If you measure it in space and measure it in air and meaure it in water it comes out the same.

If you measure it in AIR while in SPACE it seems to slow, but that is relativitity in action.

Light slows when observed from SPACE when it hits AIR and slows even more when it hits WATER, but if you measured it in AIR or WATER is is the same as in SPACE

In relativistic space if you travel at the speed of light you shrink in size and time slows down AS COMPARED to EARTH TIME, but NOT inside the ship.

If you travel around Alph Centari at half the speed of light you still age 18 years, because that's how long it takes, but in EARTH time it ins only about ONE YEAR of EARTH TIME.

It is also unclear if ORGANIC life adjusts or doesn't adjust to RELATAVISTIC time

Einstein SAYS we adjust and adjust quickly

Thus it is POSSIBLE that people travelling to Alpha Centari at half the speed of light may only age fractionally less than those on EARTH, but the CLOCKS on the ship will age FAR LESS becasue theya re atomic or mechancial.

Special relativity says that the speed of light always looks the same, whether the object is moving or still. The cool thing is that if you were moving at the same speed as the object that is emitting the light, the light moves away from you at the speed of light. But to someone standing still, it looks like you are moving along with the light, and they would think the light would look slower to you.

No, not really. Light is emitted at one speed only - the speed of light. Suppose the light is emitted from a very fast jet plane. The pilot of the plane sees the light leaving the plane at the speed of light. Suppose there's another jet plane flying directly towards the first plane. The second pilot sees the light moving towards him at... the speed of light. This counter-intuitive result is explained by the Theory of Relativity. Light appears to move at the same speed regardless of the speed of the observer.

No, the speed of light is constant.

What changes is the frequency. A light emitting object coming at you has a higher frequency than the same object going away from you. That's the Doppler effect.

no the speed of light is measure relative to the observer

fake. Doppler Shift transformations its wavelength which in turn transformations frequency of the easy. and you already know, speed is : wavelength x freq , so the two replace (one will boost and the different decreases) and speed continues to be the comparable.

Hi. Yes, assuming the relativistic effects are accounted for.

no, light would not be affected by the objects velocity...
