Using the velocity transformation formula, calculate the speed in the "rest frame" of a particle which is seen to be moving at c in a "moving frame"

What will be an ideal response?


u = (v+u')/(1+vu"/c2 ) = (v+c)/(1+vc/c2 ) = c(v+c)/(c+v) = c
Light speed in one frame will be light speed in all inertial frames.
