Unformatted text preview: 1. This question is based upon a thought experiment first proposed by Einstein. (a) Define the terms proper time and proper length . Proper time: ........................................................................................................... ........................................................................................................... Proper length: ........................................................................................................... ........................................................................................................... (2) In the diagram below Miguel is in a railway carriage that is travelling in a straight line with uniform speed relative to Carmen who is standing on the platform. Miguel is midway between two people sitting at opposite ends A and B of the carriage. A B Miguel Carmen platform At the moment that Miguel and Carmen are directly opposite each other, the person at end A of the carriage strikes a match as does the person at end B of the carriage. According to Miguel these two events take place simultaneously. (b) (i) Discuss whether the two events will appear to be simultaneous to Carmen. ........................................................................................................................... ........................................................................................................................... ........................................................................................................................... ........................................................................................................................... ........................................................................................................................... (4) 1 (ii) Miguel measures the distance between A and B to be 20.0 m. However, Carmen measures this distance to be 10.0 m. Determine the speed of the carriage relative to Carmen. ........................................................................................................................... ........................................................................................................................... ........................................................................................................................... ........................................................................................................................... (2) (iii) Explain which of the two observers, if either, measures the correct distance between A and B? (2) (Total 10 marks) 2. This question is about electrons travelling at relativistic speeds. A beam of electrons is accelerated in a vacuum through a potential difference V ....
