Hello There, I have basic doubt about light propagation .So I'm hoping to get some help here. The problem is ...Let us assume two frames, 'MOVING FRAME'[one moving with a certain velocity(constant)] and 'REST FRAME'[one wrt to which the first frame is moving]. If now moving frame emits a laser beam ...I want to know how the path of that laser will look like in both the frames mentioned above. I'll ask further doubts depending on the answer I'll get. Thanx for helping in advance.
