Reference frames in relativity

[nemzy]

why is it that when two events occur simultaneosuly at separated points on the x-axis of reference fram S, the observer moving in the positive X direction sees the event withe largest x coordinate first

shouldnt it be the smallest?

nm i reread my book and found the answer thanks

In relativity, reference frames are used to describe the position and movement of objects in space and time. These frames are relative to each other and can be moving at different velocities. This means that different observers may perceive the same event differently depending on their relative motion.

In the scenario described, the observer is moving in the positive X direction, which means they are moving towards the events on the x-axis with a certain velocity. This velocity affects the perception of time for this observer, causing time to appear to pass slower for them compared to a stationary observer. This phenomenon is known as time dilation.

As a result, the observer moving in the positive X direction will see the event with the largest x coordinate first. This is because, for them, time appears to pass slower, so the event at the larger x coordinate appears to happen first. This is in contrast to a stationary observer who would see the events occur simultaneously since they are not affected by time dilation.

In summary, the perception of time is relative to the observer's reference frame and their relative motion. This is a fundamental concept in relativity and helps explain why events may appear to occur in a different order for different observers.
