Consider Alice’s spaceship with the light pulse apparatus that shoots two light pulses toward clocks at opposite ends of her ship, each with speed c relative to the apparatus (as drawn in the video lecture). Assume that Alice has properly synchronized her clocks, that her spaceship is moving with speed V to the right (in the positive x direction) relative to Bob, and that c is greater than V. True or false: In Alice’s frame of reference, the two light pulses will hit the clocks simultaneously (i.e., each clock will read the same time when the light pulses hit).

2. Question 2 Consider a situation that is similar to that in one of the video lectures, i.e., Alice observing Bob traveling from Earth to a star at a certain…

8. Question 8 If the spaceship in the “faster than light?” example travels from San Francisco to St. Louis at a speed of 0.5c, how fast does the ship appear…

4. Question 4 True or false: Einstein was a thorough-going revolutionary, who wanted to move beyond the old, classical theories and ways of doing physics. 1 point   True False

4. Question 4 Which world line represents an object that is moving with a varying velocity along the x axis? 1 point  

9. Question 9 Consider two identical light clocks, designed as explained in lecture. Bob has one, and Alice takes the other on her spaceship and flies by Bob at speed…

1. Question 1 What is the “photo clock principle”? 1 point   The idea that photographs cannot be trusted if they don’t have a timestamp on them. The idea that…
