Michelson and moreley find out that there is no fringe in the light beam coming from two arms of interferometer. Thia indicates that light takes the same time along any direction. This proved that speed of light is constant, independent of frame of reference.
The discovery that was made from their results that ether does not exist.

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 × 10−15 s) when the apparatus is rotated by 90◦. what velocity through the ether would be deduced from a shift of one fringe? (Take the length of the interferometer arm to be 11 m.)

Any information on how to answer these?
The speed of light depends on the medium through which it travels, and it is generally slower in the denser media. Fermat's principle in optics asserts that light travels from one point to another along a path for which the time of travel is minimum. In a uniform medium, where the speed of light remains constant, "shortest time" means "shortest path", and the ray of light follows a...

The speed of light in some other universe is 30 m/s. You want to cover a distance of 100 m in 10 s (as measured on your watch) at a constant speed. a. How fast should you run? b. How long did it take you to cover that distance according to an observer at rest with respect to the track? (Carry four sig figs throughout the calculation).

A scientist measured the speed of light. His values are in km/sec and have 299,000 subtracted from them. He reported the results of 22 trials with a mean of 756.22 and a standard deviation of 112.75. a) Find a 90% confidence interval for the true speed of light from these statistics. b) State in words what this interval means. Keep in mind that the speed of light is a physical constant that, as far as we know, has a value...

For an independent study project, you design an experiment to measure the speed of light. You propose to bounce laser light off a mirror that is 46.5 km due east and have it detected by a light sensor that is 105 m due south of the laser. The first problem is to orient the mirror so that the laser light reflects off the mirror and into the light sensor. (a) Determine the angle that the normal to the mirror should...
