The control panel on a spaceship contains a light that blinksevery 1.81 s as observed by an astronaut in the ship. If thespaceship is moving past Earth with a speed of 0.793c,determine the proper time interval between blinks and the timeinterval between blinks as observed by a person on Earth.
(a)
the proper time interval (in s) between blinks
s
(b) the time interval (in s) between blinks as observed by aperson on Earth
s
