The control panel on a spaceship contains a light that blinks every 2.96 s as observed by an astronaut in the ship. If the spaceship is moving past Earth with a speed of 0.723c, determine the proper time interval between blinks and the time interval between blinks as observed by a person on Earth. HINT (a) the proper time interval (in s) between blinks S (b) the time interval (in s) between blinks as observed by a person on Earth S
