Question

(i) Using the appropriate Lorentz transforms, transform all four events into the Spaceship frame and list their coordinates. (ii) What time is shown on the Spaceship clock when the radio signal arrives? (iii) By comparing the position and time coordinates of the relevant events, calculate the speed of the radio signal as measured in the Spaceship frame.[2] (iv) As measured in the Spaceship frame, how far has the Earth moved between the Spaceship passing Earth and the Spaceship arriving at the Moon?[2] (v) Draw labelled diagrams showing the emission and arrival of the radio signal as seen from the Spaceship frame. Indicate the relative positions of the Earth, Moon and radio signal in each, and note the position and time coordinates of each event on your diagrams. [6]
