The Experiments Alice Is Standing In A Field And Bob Is Riding On A Railroad Car That Is Moving With Velocity V Bob Shi 1 (111.69 KiB) Viewed 11 times

The experiments Alice is standing in a field and Bob is riding on a railroad car that is moving with velocity v. Bob shines a flashlight in the direction in which he is moving. Question: With what speed does each observer see the light travelling? Alice and bob (both in inertial frames) are floating in an empty universe with the same laws of Physics as ours. Alice sees herself as stationary, but Bob is moving to her left with a constant velocity. Bob disagrees. He sees himself as stationary, and Alice is moving past to his right with a constant velocity. Question: Can you design any experiment which will be able to determine who is correct? 00
Bob is on a railroad car moving to the right with a constant velocity. On his car are two light bulbs that, from his perspective, switch on simultaneously. Will Alice agree that the lights switch on simultaneously. Hint, she will agree that the light from each of the bulbs arrive at Bob simultaneously. Click on these two links for some hints for this question from Alice's perspective and from Bob's perspective. 00
Alice is standing in a field (on a planet without gravity) and she sees two simultaneous flashes of lightning (that is the light from each arrives at her position at the same time). Bob is on a railroad car moving to the right with a constant velocity. Question 3b: Does Bob think that the lightning strikes occurred simultaneously? If not, which flash does Bob think occurred first? Question 3c: How are experiments 3a and 3b similar. How are they different?
Alice is standing in a field. Next to her is a light clock. That is, two mirrors that are reflecting a beam of light back and forth, and the journey from one mirror to the other and back again counts as one tick of the clock. 00 Standing on a railroad car is Bob. He has an identical light clock. The railroad car is not moving. Question 4a: Do Alice and Bob's light clocks stay synchronized. II
