Archie drew a diagram to represent how light that casts a beam through a spaceship appears to an observer. Each line in the diagram represents the beam of light as seen by the observer.
Which labels best complete the diagram?
A. X: observer is on the ground, spaceship is at rest on the ground
Y: observer is inside the spaceship, spaceship is traveling at a constant velocity
Z: observer is on the ground, spaceship is traveling at a constant velocity
B. X: observer is on the ground, spaceship is traveling at a constant velocity
Y: observer is inside the spaceship, spaceship is accelerating
Z: observer is on the ground, spaceship is traveling at a constant velocity
C. X: observer is inside the spaceship, spaceship is accelerating
Y: observer is inside the spaceship, spaceship is traveling at a constant velocity
Z: observer is inside the spaceship, spaceship is at rest on the ground
D. X: observer is inside the spaceship, spaceship is traveling at a constant velocity
Y: observer is inside the spaceship, spaceship is accelerating
Z: observer is inside the spaceship, spaceship is at rest on the ground
