| 31. | Total path length was with a path width of.
|
| 32. | The average path length depends on the system size but does not change drastically with it.
|
| 33. | If the optical path length variations are more than a wavelength the image will contain fringes.
|
| 34. | But weighted path lengths have an interesting property.
|
| 35. | The tornado itself was estimated to have been wide and have had a path length of.
|
| 36. | Path lengths up to 20m are commercially available.
|
| 37. | The coefficient gives the number of secondary electrons produced by primary electron per unit path length.
|
| 38. | The optical path length is constant between wavefronts.
|
| 39. | Dividing the path length of a particle track by the time of travel gives the speed.
|
| 40. | To see this, consider what Knuth calls the " weighted path length " of a tree.
