Problem 2.3: A spaceship flies close to a space beacon at 70% of c

Please wait for the animation to completely load.

A spaceship flies close to a space beacon at 70% of the speed of light (position is given in meters and time is given in 10−5 seconds). The beacon emits light flashes as shown in the animation. What is the time difference between these light flashes as seen by an observer inside the space ship?  The time shown in the upper left hand corner is the time as measured in the reference frame of the beacon. Restart.
