Paragraph : A spaceship traveling east flies directly over the head of an inertial observer who is at rest on the Earth's surface. The speed of the spaceship can be found from this relationship: sqrt(1-v^(2)//c^(2))=1//2. The navigator of the space ship observes a neon sign on a storefront. If he measures the speed of light emitted from the sign as he approaches the sign, what value will he obtain? |
