Clicker Exercise
A ``light clock'', described in the class, has proper length L0.
It keeps on tic-tac. In the ground frame, the clock is flying at
v=0.6 c along the clock axis direction.
How long does it take the light signal to travel from the source to the
mirror in the frame comoving with the clock?
(a) [(L0)/0.6 c]
(b) [(L0)/0.8 c]
(c) [(0.6L0)/0.8 c]
(d) [(0.8L0)/0.6 c]
(e) [(L0)/c]
(f) [(0.8 L0)/0.4 c]
(g) [(0.8 L0)/1.6 c]
How long does it take the light to travel from the source to the mirror
in the ground frame?

(b) [(L0)/0.8 c]
(c) [(0.6L0)/0.8 c]
(d) [(0.8L0)/0.6 c]
(e) [(L0)/c]
(f) [(0.8 L0)/0.4 c]
(g) [(0.8 L0)/1.6 c]
How long does it take the light to travel back to the sensor from the mirroe
in the ground frame?

(d) [(0.8L0)/0.6 c]
(e) [(L0)/c]
(f) [(0.8 L0)/0.4 c]
(g) [(0.8 L0)/1.6 c]
