Albert is piloting his spaceship, heading east with a speed of 0.94 c relative to Earth. Albert's ship sends a light beam in the forward (eastward) direction, which travels away from his ship at a speed c. Meanwhile, Isaac is piloting his ship in the westward direction, also at 0.94 c, toward Albert's ship. With what speed does Isaac seeAlbert's light beam pass his ship?
