i have a question about chapter 37.2 relativity of simultaneity (pearsons international edition university physics, 12th edition) .
the text besides image b sais: inside the train, mavis moves toward the light coming from the front of the train and away from the light coming from the back of train.
then image c shows the light from the front of the train reaching her first, in my understanding, this implies mavis sees the flashes at different times because she is moving towards the origin of one of the flashes.
this is very confusing to me, because what i learned in the previous chapter tells me that cA' = cB' no matter how the train moves.
Above statement is correct right?!
if it is, then why does it look like the images are trying to tell me cA' < cB' in mavis' frame.
