About emitted beam and reflected beam of "Orbis" or "speed gun", the formula : lightspeed = frequency x wavelength is as follows. At observer (at stand-still in the air) : Lightspeed is equal. Frequency & wavelength is not equal. At moving object : Frequency is equal. Lightspeed & wavelength is not equal.

In the outer space, lightspeed is not equal at both (observer and moving object).
