Constancy of Speed of Light in Minkowski Diagram
This section provides a demonstration of constancy of speed of light using a Minkowski diagram.
The main assumption of the special theory of relativity is that the speed of light has the same value c measured in all inertial frames.
This assumption can be easily demonstrated by the Minkowski diagram. Let's follow a simple thought experiment described below:
Now let's assume that Amy's frame is moving at a speed of v=0.6*c:
So the speed of light is 1 (c) in both Bob's frame and Amy's frame.
