Time Dilation in Minkowski Diagram
This section provides a demonstration of the time dilation phenomenon using a Minkowski diagram.
Minkowski diagram can also be used to demonstrate the time dilation phenomenon.
Let's follow another simple thought experiment described below:
- Amy stays in frame moving at a speed of v=0.6*c relative to Bob's frame.
- Amy holds a clock in her frame at (0,0) as event O.
- Amy waits for 4 seconds at arrives at event E, (X',cT')=(0,4).
- The elapsed time of E in Amy's frame is cT'=4 seconds.
Now in Bob's frame:
- The event E would be observed at (X,cT)=(3,5) in Bob's frame
based on the Minkowski diagram given below.
- The elapsed time of E in Bob's frame is cT=5 seconds.
So the elapsed time in Amy's moving frame is dilated by cT/cT' = 5/4 = 1.25,
which matches Lorentz factor of the time dilation formula presented earlier in the book.
