Answer #1

Option a and b are true as speed of light is independent of frame of reference. It is the 2nd law of special theory of relativity given by Einstein. Weather in inertial or non inertial frame, speed of light remain constant.

    Velma's rocket ship is moving away from Mort at a speed of 0.75c. Mort fires a laser beam toward her spaceship, observing the tip of the laser beam to move away from him at speed c. Velma observes this laser beam to move past her at a speed of 1.75c. 1.25c. 0.25c. 0.75c. None of the above. We know that light is quantized because, in the double slit experiment with light, when one slit is closed, no interference pattern shows...
