QUESTION 28

Two laboratories move at constant velocity relative to one another. Each laboratory performs the same mechanics experiment and measures the speed of the same light pulse in vacuum. Which result is consistent with special relativity?
(A)
Both laboratories obtain the same laws of physics and both measure the light pulse at cc.
(B)
Only the stationary laboratory may use the usual laws of physics.
(C)
The laboratory moving toward the pulse measures a speed greater than cc.
(D)
The light speed changes with the speed of its source.
