One of the difficulties with the Michelson Morley experiment is that several extraneous effects (mechanical vibrations, variations of temperature, etc) can produce unwanted shifts in the interference pattern, masking the expected shift of interest. Suppose, for example, that during the experiment the temperature of one arm of the interferometer were to rise by deltaT. This would increase the arm’s length (L) by delta(L) =aLdeltaT, where a=10-5 is the arm’s coefficient of expansion. a) Symbolically, express the shift delta(N) that this temperature change would cause (in terms of a, L, deltaT, and lamda).b) Calculate deltaN for lamda=590nm, L=50cm, and deltaT=0.01 C. c) Make a conclusion about the importance of careful temperature control in the experiment by comparing result in b) with the expected shift deltaN (without temperature correction). Hint: we calculated the expected shift in class for different dimensions of the Michelson Interferometer.

- Two astronomical events are observed to occur at a time of 0.30 s apart and a distance separation of 2.0109m from each other. How fast must a spacecraft travel from the site of one event toward the other to make the events occur at the same time when measured in the frame of reference of the spacecraft?arrow_forwardMuons are unstable subatomic particles that decay to electrons with a mean lifetime of 2.2 µs. They are produced when cosmic rays bombard the upper atmosphere about 10 km above the earth’s surface, and they travel very close to the speed of light. The problem we want to address is why we see any of them at the earth’s surface. (a) What is the greatest distance a muon could travel during its 2.2 µs lifetime? (b) According to your answer in part (a), it would seem that muons could never make it to the ground. But the 2.2 µs lifetime is measured in the frame of the muon, and muons are moving very fast. At a speed of 0.999c, what is the mean lifetime of a muon as measured by an observer at rest on the earth? How far would the muon travel in this time? Does this result explain why we find muons in cosmic rays? (c) From the point of view of the muon, it still lives for only 2.2 µs, so how does it make it to the ground?

- Michelson-Morley Experiment. A shift of one fringe in the Michelson-Morley experiment corresponds to a change in the round-trip travel time along one arm of the interferometer by one period of vibration of light (about 2 X 10-15 s) when the apparatus is rotated by 90.

You esti- mate that you can measure the r and y positions with uncertainty +0.003 m. The frame rate of the video is 30 frames/s, which means the time interval between frames is At = 0.033 333 s. The uncertainty of the frame rate of a video camera is VERY small. For the sake of this prob- lem, use 8(At) = 1 x 10-6 s. The mass of the marble is (2.031 +0.001) x 10-2 kg. Calculate the following quantities: 4. The value of the momentum component p = mv, and its uncertainty, 5. The value of the momentum component py = muy and its uncertainty, and 6. The value of the kinetic energy K = mv² = m(v² + v²) and its uncertainty.arrow_forward
