Light sources A & B begin at the same location. Then, source A begins moving directly (and soon inertially) away from Observer at 0.8c, while source B begins moving directly (and soon inertially) toward Observer at 0.8c. SR Doppler redshift causes the light received by Observer from A to be redshifted, and the light from B to be blueshifted. Light from A is redshifted because the wavecrests look stretched apart, and light from B is blueshifted because the wavecrests look compressed together. However, SR time dilation causes Observer to perceive that BOTH A's and B's clock run slower than Observer's clock. In general, in its rest frame an observer perceives an inertially moving object's clock to run slower than the observer's own clock, regardless of the direction of movement. Light originating from a slower clocked source, when viewed in a reference frame with a faster clock, creates a redshifting effect. Does the Lorentz tranformation time dilation cancel out the Lorentz transformation blueshift from source B, and double the Lorentz transformation SR Doppler redshift from source A, as perceived by Observer?
