Document Summary

Eternity is very long, especially towards the end. woody allen: (10 marks) A young inventor combined a timer with a laser pointer (call the device a lamer) such that the laser pointer is turned on when the timer goes o . The laser light is red in colour (wavelength of 700 nm). What frequency would the girl in the station observe for the light from the lamer? (2 marks: (8 marks) Two atoms, a and b, have an inelastic collision. The result of the collision is two di erent atoms, c and d. that is, there are two atoms before the collision and only. The rest masses of atoms a, b, and c are 3 gev/c. In the lab frame, atom a was observed to be coming in and 6 gev/c from the left at 0. 8c and atom b was coming in from the right at 0. 6c. After the collision, atom c was at rest in the lab.
