Question

An astronaut is out in space with an extremely precise timing device measuring the speed of various fast‑moving objects. A laser gun is mounted on a spaceship and aimed forward. As the spaceship flies toward the astronaut at a speed of 200 million m/s, the laser shines a beam of light toward him.

Determine the speed that would be measured in each of the cases listed.

- speed of the laser light as measured in the astronaut's reference frame

-speed of the laser light measured in the spaceship's reference frame

-the speed of the laser gun as measured in the astronaut's reference frame

-the speed of the laser gun measured in the spaceship's reference frame.
