| 21. | Those electrons, however, are all individually described by wave fronts that expand in all directions from the point of entry.
|
| 22. | So as with ether concept, wave front reaches upper mirror in t _ { to \ upper } = BC'/ c.
|
| 23. | As the seas begin to build up, you can come down those wave fronts and hit speeds in the high 20s,
|
| 24. | The combustion creates two pressure wave fronts, one traveling down the longer exhaust tube and one down the short intake tube.
|
| 25. | The St . Jude storm formed from a wave front on 26 October in the northwest Atlantic off the explosive deepening.
|
| 26. | On the surface, this produces a series of wave fronts, spaced about 600 miles apart, that move west 30 miles a day.
|
| 27. | However their model is not a cellular automaton because the medium in which signals propagate is continuous, and wave fronts are curves.
|
| 28. | At the same time the intensity of the Arago spot is reduced with respect to the intensity of the undisturbed wave front.
|
| 29. | Prior to wave reflection, they both are characterized by a steep wave front followed by a nearly exponential decay at close distances.
|
| 30. | The wave front set is defined such that its projection on " X " is equal to the singular support of the function.
