Michelson-Morley Experiment. A shift of one fringe in the Michelson-Morleyexperiment corresponds to a change in the round-trip travel time along one armof the interferometer by one period of vibration of light (about 2 X 10-15 s) whenthe apparatus is rotated by 90. Based on the results of such experiment, whatvelocity through the ether would be deduced from a shift of one fringe? (Take thelength of the interferometer arm to be 11 m.)

[Spacetime and General Relativity] Suppose a human-made satellite in outer space detects light with wavelength λ coming from the surface of a distant planet with mass M and radius R. What is the wavelength of the light as measured by a device on the planet’s surface? Suppose both the device and the satellite are at rest with respect to the planet.
Your video analysis of the motion of a marble gives it position in frame 23 as (x23, Y23) = (0.134 m, 0.120 m) and its position in frame 24 as (x24, 324) = (0.122 m, 0.112 m). 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.
Hand written solution plz.
It has been proposed that spacecraft could be propelled by emitting intense beams of EM radiation from their tails rather than high-velocity chemical exhaust. This could reduce the fuel load required, which is very large for chemical rockets. Suppose a spacecraft (M = 250,000 kg) is floating in empty space at rest relative to a nearby space station. It then emits a very powerful 10.0 MW beam of laser light for one full day from its tail. Calculate the velocity acquired by the vehicle relative to the space station due to this emission of EM radiation
i) Contrast the processes of induced and spontaneous emission. We need to know the meaning of Einstein's coefficients. ii) What is the frequency difference between the 20th and 21st resonant longitudinal modes if the cavity length is 20 cm?
