| 31. | The control electronics required to sense and drive the standing waves, is somewhat sophisticated.
|
| 32. | Below this frequency, the field is not diffuse and standing waves create pressure modes
|
| 33. | The standing waves created by the mismatch are periodic regions of higher than normal voltage.
|
| 34. | Light confined in the cavity reflects multiple times producing standing waves for certain resonant frequencies.
|
| 35. | Furthermore, standing waves are practically eliminated as there are no parallel surfaces reflecting sound waves.
|
| 36. | :Between two mirrors you will get a standing wave.
|
| 37. | The amount the attenuation had to be increased is the VSWR of the standing wave.
|
| 38. | The maximum is then calculated from the known mathematical shape of the standing wave pattern.
|
| 39. | This observation explains the presence of focused bands of fluorescence in these standing wave studies.
|
| 40. | The resulting photographs of standing wave patterns are striking.
