Simultaneity of Events, Do I Have it Right?

Click For Summary
SUMMARY

This discussion clarifies the concept of simultaneity in the context of special relativity. When an observer moves at 90% the speed of light (c) and passes two stationary light bulbs, they perceive the light from the bulb in front to reach them before the light from the bulb behind. Conversely, the stationary observer, equidistant from both bulbs, perceives the light from both bulbs reaching them simultaneously. The discussion confirms that the moving observer's frame of reference leads to a different conclusion about the timing of light emissions compared to the stationary observer.

PREREQUISITES
  • Understanding of special relativity principles
  • Familiarity with the concept of light speed (c)
  • Knowledge of reference frames in physics
  • Basic grasp of simultaneity in physics
NEXT STEPS
  • Study Einstein's theory of special relativity in detail
  • Explore the implications of time dilation and length contraction
  • Learn about Lorentz transformations and their applications
  • Investigate the concept of simultaneity in different reference frames
USEFUL FOR

This discussion is beneficial for physics students, educators, and anyone interested in the principles of relativity and the nature of time and simultaneity in different frames of reference.

Ok, I want to make sure I understand this correctly.

Let's say I'm moving at 90% c and pass a light bulb that is at rest with another light bulb in the distance. In the frame of reference of an observer equidistant from the light bulbs, they flash at the same time that I my distance from each is equal. IE when I pass the observer. The observer concludes that the light from the bulb in front of me hits me before the light from the back bulb.

Now, from my frame, I see that the front bulb emits light before the back bulb, and would not say that the lights emitted light at the same time.

Alright, now let's say that I have a light bulb that I flash when I see myself pass the observer. Occording to my frame I conclude that the light hits the front light bulb before the back one. However the observer sees my light hit both bulbs at the same time.

Is all that correct?
