Motion of Train vs Platform: A Radiation Comparison

[sharma_satdev]

the frequency of radiation emitted when electron and positron are annihilated in the moving carriage is more than the the frequency of radiation emitted when the same experiment is done on railway platform .Is it not enough to decide that the motion of the train is real while platform motion is apparent

no

Standing on the platform looking at the train, you see higher frequency, while standing on the train you see lower frequency.

Doing the exact mirror experiment with the positron and electron pair located on the platform instead, yields exact mirror results.

There's no way to determine which answer is the correct one.
