Consider a clock, which when at rest produces a flash of light every second, moving away from you at (4/5)c. (a) How frequently does it flash when it is moving at (4/5)c? (b) By how much does dis- tance between you and the clock increase between flashes? c) How much longer does it take each flash to get to your eye than the previous one? (d) What, therefore, is the in- terval between the flashes vou see? You will find...

2. An observer S sees a flash of red light 1200 m from his position and a flash of blue light straight line. He measures the time interval between 720 m closer to him and on the same the occurrences of the flashes to be 5 microseconds, the red flash occurring first. a.
