∟The Relativity of Simultaneity

This chapter provides an introduction of the relativity of simultaneity in special relativity. Topics include the definition of the relativity of simultaneity; a thought experiment showing the relativity of simultaneity.

What Is the Relativity of Simultaneity

Formula for the Relativity of Simultaneity

Takeaways:

• The relativity of simultaneity in special relativity refers to the phenomenon where two events happening in two different locations that occur simultaneously in one reference frame, occur non-simultaneously in another reference frame that is moving relatively.
• Time difference of two simultaneous events observed in a moving frame is L*v/(c**2-v**2).
