yes. I know speed of light is constant in all inertial frame of reference. So how can we treat them like ball?
let me clear my question.. When mirrors move,why photon of light come with the mirrors? Why it doesn't stay in its own position?
how can we treat light like a ball? How lorentz tranformation can explain this with the assumption that light's velocity needs to be same for all inertial observers?
Think of light as a photon, as a "ball". The lorentz tranformation is based on the assumption that light's velocity needs to be same for all inertial observers.
ok.then we can treat photon like a ball but speed of light is not changing,only direction is...Right?
ok.let me clarify a little bit more. Ball moves in slanted direction in reference to a observer because ball is affected by inertia by the motion of the train. Likewise,light is affected by inertia caused by motion of mirrors but speed of light is constant. Am i right?
if you are sure that same applies to ball,then discussion is enough on this topic. I exactly know what happens to ball.i studied it.. So what i said earlier is language barrier.but i would like to say sorry for disturbing you eram...

It doesn't really from the frame that the beam is sent, it would just appear that way from another frame. A body in constant motion sending a light beam then observing it to travel in straight lines then would mean that it's motion did nothing to the light beam. If it sent it at an angle from the frame that sent the beam, then there would be a noticable effect from the velocity of the object and the light beam. It would be like sitting in your room and shinning a flashlight and then you notice it goes in a straight line, but say a space ship of alien abductees then spied in your bedroom. They would still observe the flashlight to travel in a straight line relative to you in your room even though they saw you traveling at relative speeds to them with the Earth. If you saw the beam travel at a slant in your room, then an outside observer could say that your motion then had an effect on the angle the beam was sent. That is part of another reason why there is no aether. There isn't an absolute rest to the light beam itself. So then your motion doesn't make it move at a slant from the frame that is in motion. You could travel at any constant speed you like, and then you would notice that your headlights still work the same way.
You got that right. How does it add a vector but not speed? Google "vertical velocity transformations relativity"
This is the question i asked!! You did answered it correctly.. But thank you for giving me information to look into google!!!
well,the thing is that lorentz addition of velocities require relativie velocity to be less than speed of light and it also shows that speed of light is constant when we compare it with any frames of reference. So we can have its velocity to change... Right? It that you mean? By velocity i mean direction and speed. By velocity of light change,i mean direction change but speed of light is constant..
